                   ABOUT INVERNESS MEDICAL INNOVATIONS, INC.

    We develop, manufacture and market consumer healthcare products, including
self-test diagnostic products for the women's health market and vitamins and
nutritional supplements. To a lesser extent, we develop, manufacture and market
clinical diagnostic products for use by medical professionals. Our consumer
self-test diagnostic products allow individuals to obtain accurate information
regarding various medical conditions on a confidential, non-prescription basis,
without the expense, inconvenience and delay associated with physician visits or
laboratory testing. This information gives individuals greater control over
their health and their lives, allowing them to make informed decisions and take
action to protect their health, alone or in consultation with healthcare
professionals. Our existing self-test products are targeted at the women's
health market, one of the largest existing markets for self-care diagnostics,
and include home pregnancy detection tests and ovulation prediction tests. We
also sell a wide variety of vitamins and nutritional supplements. Our clinical
diagnostic products include test kits used by smaller laboratories, physicians'
offices and other point-of-care sites for the detection of pregnancy and a wide
variety of infectious diseases.

    Inverness Medical Innovations, Inc. is a Delaware corporation. Our principal
executive offices are located at 51 Sawyer Road, Suite 200, Waltham, MA 02453.
Our telephone number is (781) 647-3900. Our website is

Stock Exchange under the symbol "IMA."

                                  THE OFFERING

    This prospectus relates to up to 5,560,238 shares of our common stock that
may be offered for sale by the selling stockholders. The shares include up to
(1) 5,053,826 shares of common stock issued or issuable upon the conversion of
Series A Convertible Preferred Stock and (2) 506,412 shares of common stock
issuable upon the exercise of warrants. We are registering the common stock
covered by this prospectus in order to fulfill our contractual obligations to do
so, which we undertook at the time of the original issuance of the shares of
Series A Convertible Preferred Stock and the warrants. Registration of the
common stock does not necessarily mean that all or any portion of such stock
will be offered for sale by the selling stockholders.

    We have agreed to bear the expenses of the registration of the common stock
under federal and state securities laws, but we will not receive any proceeds
from the sale of any common stock offered under this prospectus.

                              PLAN OF DISTRIBUTION

    The selling stockholders may sell the securities through agents or dealers,
directly to one or more individuals, institutional or other purchasers or
through any combination of these methods of sale. The distribution of the
securities may be effected in one or more transactions at market prices then
prevailing at the time of sale, at prices related to such prevailing market
prices, or at negotiated prices. See "Plan of Distribution."

                                  RISK FACTORS

    There are various risks, including those described below, which may
materially impact your investment in our company or may in the future, and, in
some cases already do, materially affect us and our business, financial
condition and results of operations. You should consider carefully these factors
with respect to your investment in our securities. This section includes or
refers to certain forward-looking statements; you should read the explanation of
the qualifications and limitations on such forward-looking statements on page 17
of this prospectus.

RISKS RELATED TO THE SPLIT-OFF

    On November 21, 2001, we were split-off from Inverness Medical
Technology, Inc. (IMT), our former parent, and became an independent, publicly
owned company as part of a transaction by which IMT was acquired by Johnson &
Johnson. Prior to that time, we had been a majority owned subsidiary of IMT, and
the businesses that we acquired in connection with the restructuring that
preceded the split-off represented approximately 20% of IMT's net product sales
during the calendar quarter concluded immediately prior to the split-off. We
continue to face a unique set of challenges and risks arising out of the
split-off.

OUR BUSINESSES WILL FACE CHALLENGES AS PART OF A STAND-ALONE COMPANY THAT WE DID
NOT EXPERIENCE AS PART OF IMT.

    As an independent, publicly owned company, we now face new issues and
challenges that we did not experience when we were part of IMT. Examples of
potential issues include:

    - our inability to rely on the long-term financial strength of IMT;

    - our inability to rely on the earnings, cash flow, assets and goodwill of
      IMT's diabetes business;

    - our inability to rely on the experience and business relationships of some
      personnel who remained with IMT;

    - greater difficulty in obtaining financing on terms satisfactory to us, if
      needed;

    - greater difficulty in obtaining and maintaining insurance on terms that
      are acceptable to us;

    - increased costs of hiring and retaining employees in departments
      previously shared by all the businesses of IMT, including the legal, risk
      management, tax, treasury, human resources and public relations
      departments; and

    - generally increased overhead and administrative costs as a result of
      establishing a stand-alone company.

We may not resolve these issues or overcome these challenges. As a result, we
may not succeed in generating and expanding customer relationships, containing
costs and expenses and enhancing our business. In addition, competitive and
market factors specific to the consumer diagnostics, vitamins and nutritional
supplements and clinical diagnostics industries will more significantly impact
our smaller, less diversified company.

OUR BUSINESSES TRADITIONALLY RELIED ON IMT FOR FINANCIAL ASSISTANCE AND MAY HAVE
DIFFICULTY WITH LIQUIDITY AND CAPITAL REQUIREMENTS WITHOUT THIS ASSISTANCE.

    Prior to the split-off, our businesses relied on the earnings, assets and
cash flow of IMT for liquidity, capital requirements and administrative
services. In the past, when the liquidity needs of our businesses exceeded their
cash flow, IMT provided the necessary funds. As a result of the split-off, we
can no longer rely on IMT for financial assistance. Accordingly, if we are
unable to generate sufficient cash flow or borrow sufficient amounts under our
credit facilities to fund our working capital needs and

                                       2

to pay our debts, we will need to obtain additional financing. We do not know if
we can obtain additional financing or if the terms of any required financing
will be acceptable to us. If we are unable to fund our working capital needs and
additional growth through our existing credit facilities, cash flow, or
additional financing, or if additional financing is not available under
acceptable terms to us, our business prospects, results of operations, cash flow
and future growth will be negatively affected.

OUR HISTORICAL FINANCIAL INFORMATION MAY NOT BE REPRESENTATIVE OF OUR RESULTS AS
A SEPARATE COMPANY.

    The historical financial information included in our annual report on
Form 10-K, as amended, for the year ended December 31, 2001 reports on time
periods prior to the split-off and reflect the operating history of our
businesses when they were a part of IMT. As a result, this financial information
may not reflect what our results of operations, financial position and cash
flows would have been had we been a separate, stand-alone company during the
periods presented. This financial information also may not reflect what our
results of operations, financial position and cash flows will be in the future.
This is not only related to the various risks associated with the fact that we
have not been a stand-alone company, but also because:

    - various adjustments and allocations were made to the financial statements
      in our annual report on Form 10-K because IMT did not account for us as a
      single stand-alone business for any period presented; and

    - the information does not reflect many significant changes that occurred in
      our financial condition, capital structure and operations as a result of
      our separation from IMT.

The adjustments and allocations we made in preparing our financial information
may not appropriately reflect our operations during the periods presented as if
we had operated as a stand-alone company.

THE CHANGE OF SOME PERSONNEL IN OUR COMPANY IN CONJUNCTION WITH THE SPLIT-OFF
MAY IMPACT OUR BUSINESS.

    Some of IMT's personnel became our initial employees, while others did not.
In particular, certain significant employees of IMT who were engaged primarily
in the diabetes care products business remained with that business. In addition,
some members of IMT's management who worked substantially for IMT's diabetes
care products business became our employees. Finally, some IMT personnel who
provided services beneficial to our businesses through their work in IMT's
accounting, sales, marketing, operations, quality assurance, regulatory
compliance and other areas did not become part of our company after the
split-off or, in certain cases, their services may only be available to us on a
transitional basis for a short period of time. The loss of certain significant
employees, the transition of personnel from IMT's diabetes business to our
company and the loss of other IMT personnel who will not become our employees
may impact or disrupt our sales and marketing activities, our research and
development efforts or our administrative functions.

OUR STOCK PRICE MAY FLUCTUATE SIGNIFICANTLY AND STOCKHOLDERS WHO BUY OR SELL OUR
COMMON STOCK MAY LOSE ALL OR PART OF THE VALUE OF THEIR INVESTMENT, DEPENDING ON
THE PRICE OF OUR COMMON STOCK FROM TIME TO TIME.

    Our common stock recently became listed on The American Stock Exchange. An
active trading market in our common stock, however, may not develop or be
sustained in the future. Our common stock may experience volatility until
trading values become established. As a result, it could be difficult to make
purchases or sales of our common stock in the market at any particular time.

    IMT stockholders immediately prior to the split-off became stockholders of
our company immediately after the split-off. Some stockholders who received our
common stock in the split-off may decide that they do not want to maintain an
investment in a company involved primarily in consumer

                                       3

and clinical diagnostic products and vitamins and nutritional supplements or in
a public company that does not have a proven track record as a stand-alone
company. If these stockholders decide to sell all or some of their shares or if
the market perceives that those sales could occur, the trading value of your
shares may decline. In addition, because we will be a smaller and less
diversified company than IMT, market analysts and the investment community may
not follow our common stock as closely as they have followed IMT common stock in
the past. If there is only a limited following by market analysts or the
investment community, the amount of market activity in our common stock may be
reduced, making it more difficult for you to sell your shares.

    In addition, our share price may be volatile due to our operating results,
as well as factors beyond our control. It is possible that in some future
periods the results of our operations will be below the expectations of the
public market. In any such event, the market price of our common stock could
decline. Furthermore, the stock market may experience significant price and
volume fluctuations, which may affect the market price of our common stock for
reasons unrelated to our operating performance. The market price of our common
stock may be highly volatile and may be affected by factors such as:

    - our quarterly and annual operating results, including our failure to meet
      the performance estimates of securities analysts;

    - changes in financial estimates of our revenues and operating results or
      buy/sell recommendations by securities analysts;

    - the timing of announcements by us or our competitors of significant
      products, contracts or acquisitions or publicity regarding actual or
      potential results or performance thereof;

    - changes in general conditions in the economy, the financial markets or the
      health care industry;

    - government regulation in the health care industry;

    - changes in other areas such as tax laws;

    - sales of substantial amounts of common stock or the perception that such
      sales could occur;

    - changes in investor perception of our industry, our businesses or our
      prospects; or

    - other developments affecting us or our competitors.

WE ARE OBLIGATED TO INDEMNIFY IMT AND OTHERS FOR LIABILITIES WHICH COULD REQUIRE
US TO PAY IMT AMOUNTS THAT WE MAY NOT HAVE.

    The restructuring agreement, post-closing covenants agreement and related
agreements entered into in connection with the split-off and merger transaction
with Johnson & Johnson provide that we will indemnify IMT and other related
persons for specified liabilities related to our businesses, statements in the
proxy statement/prospectus issued in connection with the split-off and merger
about our businesses and breaches of our obligations under the restructuring
agreement, post-closing covenants agreement and related agreements. We are also
required to indemnify IMT for losses, if any, arising from the failure to amend
some outstanding warrants for the purchase of IMT common stock.

    In addition, under our tax allocation agreement with IMT and Johnson &
Johnson, we will indemnify Johnson & Johnson and IMT for any unpaid tax
liabilities attributable to the pre-split-off operation of our consumer
diagnostics, vitamins and nutritional supplements and clinical diagnostics
businesses.

    While no claims for indemnification have yet been made (and may never be
made), we are unable to predict the amount, if any, that may be required for us
to satisfy our indemnification obligations under these agreements. However, if
claims are made for indemnification and we are liable for such claims, the
amount could be substantial. In such an event, we may not have sufficient funds
available to

                                       4

satisfy our potential indemnification obligations. In addition, we may be unable
to obtain the funds on terms satisfactory to us, if at all. If we are unable to
obtain the necessary funds, we will need to consider other alternatives,
including sales of assets, to raise necessary funds.

RISKS RELATED TO OUR BUSINESS

OUR BUSINESS HAS SUBSTANTIAL INDEBTEDNESS WHICH COULD RESULT IN ADVERSE
CONSEQUENCES FOR US.

    As of December 31, 2001, we had approximately $82.7 million of outstanding
indebtedness under our credit facilities, subordinated promissory notes and
other debt-related instruments. With our acquisition of IVC Industries, Inc.
(IVC) on March 19, 2002, we assumed additional debt and capital lease
obligations totaling approximately $18.7 million. Our substantial level of debt
affects our future operations in several important ways, including the
following:

    - our ability to obtain additional financing may be impaired;

    - our flexibility to adjust to market conditions is limited, leaving us
      vulnerable in a downturn in general economic conditions or in our business
      and less able to plan for, or react to, changes in our business and the
      industries in which we operate;

    - we may need to use a large portion of our cash flow from operations to pay
      principal and interest on our indebtedness, which would reduce the amount
      of cash available to finance our operations and other business activities
      and may require us, in order to meet our debt service obligations, to
      delay or reduce capital expenditures or the introduction of new products
      and/or forego business opportunities including acquisitions, research and
      development projects or product design enhancements; and

    - we may be at a competitive disadvantage compared to our competitors that
      have less debt.

Furthermore, there can be no assurance that our cash flow from operations and
capital resources will be sufficient to pay our indebtedness. If our cash flow
and capital resources prove inadequate we could face substantial liquidity
problems and might be required to dispose of material assets or operations,
restructure or refinance our debt or seek additional equity capital.

    Additionally, the agreements governing our indebtedness subject us to
various restrictions on our ability to engage in certain activities, including,
among other things, our ability to:

    - incur additional indebtedness;

    - acquire other businesses;

    - make capital or finance lease expenditures; and

    - dispose of assets.

These restrictions may limit our ability to pursue business opportunities or
strategies that we would otherwise consider to be in the best interests of our
stockholders.

OUR CREDIT FACILITIES CONTAIN CERTAIN FINANCIAL COVENANTS AND OTHER CONDITIONS
THAT WE MAY NOT SATISFY WHICH, IF NOT SATISFIED, COULD RESULT IN THE
ACCELERATION OF THE AMOUNTS DUE UNDER OUR CREDIT FACILITIES AND THE LIMITATION
OF OUR ABILITY TO BORROW ADDITIONAL FUNDS IN THE FUTURE.

    As of December 31, 2001, we had approximately $62.4 million of outstanding
indebtedness under our various credit facilities, substantially all of which was
owed to The Royal Bank of Scotland plc and related entities. IVC, which we
acquired on March 19, 2002, has additional credit facilities under which
approximately $15.9 million was owed at the closing of the acquisition. The
agreements governing these various credit facilities subject us to various
financial and other covenants with which we must comply on an ongoing or
periodic basis. These include covenants pertaining to interest coverage, cash
flow

                                       5

coverage, leverage and EBITDA. If we violate any of these covenants, there may
be a material adverse effect on us. Most notably, our outstanding debt under one
or more of our credit facilities could become immediately due and our ability to
borrow additional funds in the future may be limited. Additionally, under the
terms of our credit facilities with The Royal Bank of Scotland plc and related
entities, if either Ron Zwanziger or David Scott ceases to be a member of our
board of directors, the full amount of our indebtedness under these credit
facilities will accelerate. Mr. Zwanziger and Dr. Scott, both of whom are
executive officers of our company, are currently serving on our board of
directors, however, there is not assurance that they will continue to do so.

RISING INTEREST RATES WOULD INCREASE OUR INTEREST COSTS AND REDUCE OUR EARNINGS.

    We currently have, and may incur more, indebtedness that bears interest at
variable rates. Accordingly, if interest rates increase, so will our interest
costs, which would adversely affect our earnings, cash flow and our ability to
service debt.

NON-COMPETITION OBLIGATIONS AND OTHER RESTRICTIONS WILL LIMIT OUR ABILITY TO
TAKE FULL ADVANTAGE OF OUR MANAGEMENT TEAM, THE TECHNOLOGY WE OWN OR LICENSE AND
OUR RESEARCH AND DEVELOPMENT CAPABILITIES.

    Members of our management team have had significant experience in the
diabetes field, technology we own or license may have potential applications to
this field, and our research and development capabilities could be applied to
this field. In conjunction with the split-off and merger, however, we agreed in
the post-closing covenants agreement not to compete with IMT and Johnson &
Johnson in the field of diabetes. In addition, Ron Zwanziger, our Chairman,
President and Chief Executive Officer, and two of our senior scientists,
Dr. David Scott and Dr. Jerry McAleer, have entered into consulting agreements
with IMT that impose similar obligations. Further, the license agreement
prevents us from using any of the licensed technology in the field of diabetes.
As a result of these restrictions, we cannot pursue opportunities in the field
of diabetes.

OUR ACQUISITIONS OF THE UNIPATH BUSINESS AND IVC MAY NOT BE PROFITABLE OR
SUCCESSFULLY INTEGRATED AND WILL RESULT IN SIGNIFICANT CHARGES AGAINST EARNINGS.

    On December 20, 2001, we acquired Unipath Limited and its associated
companies and assets (the Unipath business) from Unilever PLC (Unilever) and
certain affiliated entities. On March 19, 2002, we acquired IVC. The value of
the Unipath business and IVC to us may not be greater than or equal to their
purchase prices. Further, we cannot guarantee that we will realize any of the
benefits or strategic objectives we are seeking to obtain by acquiring the
Unipath business or IVC. In connection with accounting for the acquisition of
the Unipath business, we have recorded a significant amount of intangible
assets. Under Statement of Financial Accounting Standards (SFAS) No. 142,
GOODWILL AND OTHER INTANGIBLE ASSETS, and SFAS No. 144, ACCOUNTING FOR THE
IMPAIRMENT OR DISPOSAL OF LONG-LIVED ASSETS, we must assess, at least annually
and potentially more frequently, whether the value of goodwill and other
intangible assets has been impaired. Any reduction or impairment of the value of
goodwill or other intangible assets will result in a charge against earnings
which could materially adversely affect our results of operations in future
periods. In addition, in connection with the acquisition of the Unipath
business, the portion of the purchase price allocated to in-process research and
development projects that had not reached technological feasibility was charged
to expense during the fourth quarter of 2001. To bring these projects to
technological feasibility, high-risk development and testing issues will need to
be resolved that will require substantial additional effort and expense.

                                       6

WE COULD EXPERIENCE SIGNIFICANT MANUFACTURING DELAYS, DISRUPTIONS TO OUR ONGOING
RESEARCH AND DEVELOPMENT AND INCREASED PRODUCTION COSTS IF UNILEVER IS UNABLE TO
SUCCESSFULLY ASSIGN THE LEASE FOR THE PRIMARY OPERATING FACILITY OF THE UNIPATH
BUSINESS WHICH IS LOCATED IN BEDFORD, ENGLAND TO US.

    The primary operating facility of the Unipath business that we acquired from
Unilever is located in Bedford, England. The Bedford facility is a multi-purpose
facility that is registered with the United States Food and Drug Administration
(FDA), contains state-of-the-art research laboratories and is equipped with
specialized manufacturing equipment. This facility currently provides the
manufacturing for the Unipath business that we recently acquired, serves as our
research and development center and serves as the administrative center for our
European operations. We are currently using the Bedford facility pursuant to an
agreement with Unilever entered into in connection with our acquisition of the
Unipath business. Unilever currently leases this facility from a third party
landlord. Pursuant to the terms of Unilever's lease, however, Unilever is not
permitted to assign the lease or sublet the Bedford facility without obtaining
the prior written consent of the landlord (which consent may not be unreasonably
withheld). Unilever has not yet obtained the landlord's consent to assign the
lease to us or sublet the property to us. Although Unilever is obligated to use
its best efforts to obtain the landlord's consent to assignment and then to
pursue the assignment, and, if necessary, a sublease, through the courts, there
are no assurances that Unilever will be successful. If Unilever is unable to
successfully assign the lease to us or otherwise enable us to realize the
benefit of its lease of the Bedford facility, we may be forced to renegotiate a
lease of the Bedford facility on substantially less favorable terms or seek
alternative means of producing our products, conducting our research and housing
our European administrative staff. In either case, we may experience
manufacturing delays and disruptions to our ongoing research and development
while we are resolving these issues and increased production costs in the
future. Additionally, there are no assurances that we will be able to
renegotiate a lease for the Bedford facility on terms that are acceptable to us
or find an acceptable replacement for this facility. Any one or more of these
events may have a material adverse effect on us.

IF WE CHOOSE TO ACQUIRE OR INVEST IN NEW AND COMPLEMENTARY BUSINESSES, PRODUCTS
OR TECHNOLOGIES INSTEAD OF DEVELOPING THEM OURSELVES, THESE ACQUISITIONS OR
INVESTMENTS COULD DISRUPT OUR BUSINESS AND, DEPENDING ON HOW WE FINANCE THESE
ACQUISITIONS OR INVESTMENTS, COULD RESULT IN SIGNIFICANT DILUTION TO OUR
EXISTING STOCKHOLDERS.

    Our success depends in part on our ability to continually enhance and
broaden our product offerings in response to changing technologies, customer
demands and competitive pressures. Accordingly, from time to time we may seek to
acquire or invest in complementary businesses, products or technologies instead
of developing them ourselves. Acquisitions and investments involve numerous
risks, including:

    - the inability to complete the acquisition or investment;

    - disruption of our ongoing businesses and diversion of management
      attention;

    - difficulties in integrating the acquired entities, products or
      technologies;

    - difficulties in operating the acquired business profitably;

    - the inability to achieve anticipated cost savings;

    - potential loss of key employees, particularly those of the acquired
      business;

    - difficulties in transitioning key customer, distributor and supplier
      relationships;

    - risks associated with entering markets in which we have no or limited
      prior experience; and

    - unanticipated costs.

                                       7

In addition, any future acquisitions or investments may result in:

    - dilutive issuances of equity securities, which may be sold at a discount
      to market price;

    - use of significant amounts of cash;

    - the incurrence of debt;

    - the assumption of liabilities;

    - unfavorable financing terms;

    - large one-time expenses; and

    - the creation of certain intangible assets, including goodwill, the
      writedown of which may result in significant charges to earnings.

Any of these factors could materially harm our business or our operating
results.

MANUFACTURING PROBLEMS OR DELAYS COULD SEVERELY AFFECT OUR BUSINESS.

    We produce our consumer products in our manufacturing facilities located in
New Jersey and in Bedford, England and Galway, Ireland and our clinical
diagnostic tests in our manufacturing facilities located in Bedford and in
Yavne, Israel. Our production processes are complex and require specialized and
expensive equipment. We rely on third parties to supply production materials and
in some cases there may not be alternative sources immediately available. In
addition, until we are able to consolidate manufacturing of our vitamins and
nutritional supplements in our New Jersey manufacturing facilities, we will
continue to rely, in part, upon third parties to manufacture these products. Any
event impacting these facilities or our contract manufacturers or suppliers
could delay or suspend shipments of products, or could result in the delivery of
inferior products. Our revenues from the affected products would decline until
such time as we were able to put in place alternative contract manufacturers or
suppliers. Even though we carry business interruption insurance policies, we may
suffer losses as a result of business interruptions that exceed the coverage
available under our insurance policies.

IF WE FAIL TO MEET STRICT REGULATORY REQUIREMENTS, WE COULD BE REQUIRED TO PAY
FINES OR EVEN CLOSE OUR FACILITIES.

    Our facilities and manufacturing techniques generally must conform to
standards that are established by government agencies, including those of
European governments, as well as the FDA. These regulatory agencies may conduct
periodic inspections of our facilities to monitor our compliance with applicable
regulatory standards. If a regulatory agency finds that we fail to comply with
the appropriate regulatory standards, it may impose fines on us or if such a
regulatory agency determines that our non-compliance is severe, it may close our
facilities. Any adverse action by an applicable regulatory agency could impair
our ability to produce our products in a cost-effective and timely manner in
order to meet our customers' demands.

IF WE DELIVER PRODUCTS WITH DEFECTS, OUR CREDIBILITY MAY BE HARMED, MARKET
ACCEPTANCE OF OUR PRODUCTS MAY DECREASE AND WE MAY BE EXPOSED TO LIABILITY IN
EXCESS OF OUR PRODUCT LIABILITY INSURANCE COVERAGE.

    The manufacturing and marketing of consumer and clinical diagnostic products
involve an inherent risk of product liability claims. In addition, our product
development and production are extremely complex and could expose our products
to defects. Any defects could harm our credibility and decrease market
acceptance of our products. In addition, our marketing of vitamins and
nutritional supplements may cause us to be subjected to various product
liability claims, including, among others, claims that the vitamins and
nutritional supplements have inadequate warnings concerning side effects and
interactions with other substances. Potential product liability claims may
exceed the amount of our

                                       8

insurance coverage or may be excluded from coverage under the terms of the
policy. In the event that we are held liable for a claim for which we are not
indemnified, or for damages exceeding the limits of our insurance coverage, that
claim could materially damage our business and our financial condition.

SALES OF THE NUTRITIONAL SUPPLEMENTS THAT WE SOLD PRIOR TO ACQUIRING IVC HAVE
DECLINED EACH YEAR SINCE 1998 DUE TO THE MATURITY OF THE MARKET SEGMENTS THEY
SERVE AND THE AGE OF THAT PRODUCT LINE AND WE MAY EXPERIENCE FURTHER DECLINES IN
SALES OF THOSE PRODUCTS.

    Sales of the nutritional products that we sold prior to acquiring IVC have
declined each year since 1998 and we have budgeted for future sale declines for
those products. We believe that those products have under-performed because they
are, for the most part, aging brands with limited brand retention that face
increasing private label competition. The age of this product line means that we
are subject to future distribution loss for under-performing brands, while our
opportunities for new distribution on the existing product lines are limited.

THE VITAMIN AND NUTRITIONAL SUPPLEMENTS MARKET IS SUBJECT TO SIGNIFICANT
FLUCTUATIONS BASED UPON MEDIA ATTENTION AND NEW DEVELOPMENTS.

    Most growth in the vitamin and nutritional supplement industry is attributed
to new products that generate attention in the marketplace. Positive media
attention resulting from new scientific studies or announcements can spur rapid
growth in individual segments of the market, and also impact individual brands.
Conversely, news that challenges individual segments or products can have a
negative impact on the industry overall as well as on sales of the challenged
segments or products. Most of our vitamin and nutritional supplements products,
including most of the vitamins and nutritional products that we acquired from
IVC, serve well-established market segments and, absent unforeseen new
developments or trends, are not expected to benefit from rapid growth. A few of
the vitamin and nutritional products acquired with IVC are newer products that
are more likely to be the subject of new scientific studies or announcements,
which could be either positive or negative. News or other developments that
challenges the safety or effectiveness of these product could negatively impact
the profitability of our vitamin and nutritional supplements business.

SALES OF OUR CLINICAL DIAGNOSTICS PRODUCTS COULD SUFFER IF ECONOMIC TRENDS IN
THE HEALTH CARE INDUSTRY HARM OUR NICHE MARKET OF SMALL AND MEDIUM SIZED
LABORATORIES.

    Our Clearview-Registered Trademark- clinical diagnostic products are low
cost alternatives to expensive and time consuming centralized testing marketed
to point-of-care professionals. Orgenics sells clinical diagnostics products
targeted at a niche market of small and medium sized decentralized laboratories
in developing nations. To the extent that trends or changes in the health care
industry favor economies of scale and centralized, automated laboratory testing,
sales of our clinical diagnostics products could suffer.

REVENUE FROM OUR CLINICAL DIAGNOSTICS BUSINESS MAY DECLINE IN THE FUTURE BECAUSE
TRENDS IN THE OVERALL MARKET FAVOR DIRECT DISEASE DETECTION OVER IMMUNE RESPONSE
TESTING.

    New technologies have made it possible to directly identify the presence of
disease rather than detecting the presence of antibodies produced through an
immune response. The trend of the overall market currently favors direct
detection over antibody detection. Virus detection through nucleic acid testing,
or NAT, is already mandatory for hepatitis C virus and other markers in France,
Australia and certain other developed nations. We believe that the threat from
direct detection technology in our core market of small and medium sized
decentralized laboratories, small blood banks, physicians and other point of
care facilities, particularly in under developed nations, is several years away.
However, this trend poses a risk to our core clinical diagnostics business in
the long term.

                                       9

WE MARKET OUR ORGENICS CLINICAL DIAGNOSTICS PRODUCTS TO SMALL AND MEDIUM SIZED
CUSTOMERS IN MORE THAN 92 COUNTRIES AT CONSIDERABLE COST THAT REDUCES THE
OPERATING MARGINS IN OUR ORGENICS CLINICAL DIAGNOSTICS BUSINESS.

    Because small and medium sized laboratories are the principal customers of
our Orgenics clinical diagnostic products, we sell these products worldwide in
order to maintain sufficient sales volume. Our Orgenics clinical diagnostics
products are marketed in more than 92 countries, including many third world and
developing nations where smaller laboratories are the norm, where more expensive
technologies are not affordable and where infectious diseases are often more
prevalent. This worldwide sales strategy is expensive and results in lower
margins than would be possible if we could generate sufficient sales volume by
operating in fewer markets.

WE COULD SUFFER MONETARY DAMAGES, INCUR SUBSTANTIAL COSTS OR BE PREVENTED FROM
USING TECHNOLOGIES IMPORTANT TO OUR PRODUCTS AS A RESULT OF A NUMBER OF PENDING
LEGAL PROCEEDINGS.

    We are involved in various legal proceedings arising out of our consumer
diagnostics, nutritional supplements and clinical diagnostics business. The
current material legal proceedings are:

    - a lawsuit by Abbott Laboratories against us and Princeton BioMeditech
      Corporation, which manufactured products for our consumer diagnostics
      business while it was part of IMT, claiming, among other things, that some
      of our products relating to pregnancy detection and ovulation prediction
      infringe patents to which Abbott asserts it is the exclusive licensee;

    - a lawsuit by Becton, Dickinson and Company alleging that pregnancy and
      ovulation test kits that we sell, and which we will continue to sell
      through our consumer diagnostics business, infringe U.S. Patent
      No. 4,703,017;

    - complaints by Intervention, Inc. against us, four of our private label
      customers, whom we are defending under agreement, and certain other
      parties alleging that under Section 17200 of the California Business and
      Professions Code the defendants' labeling on their home pregnancy tests is
      misleading as to the level of accuracy under certain conditions; and

    - an action brought by 69 consumers in London alleging defects in our
      Persona contraceptive device leading to unwanted pregnancies.

Because the above claims each seek damages and reimbursement for costs and
expenses without specific amounts, we are unable to assess the probable outcome
of or potential liability arising from the lawsuits.

    In connection with our split-off from IMT, we agreed to assume, to the
extent permitted by law, and indemnify IMT for, its liabilities in these
lawsuits together with any other liabilities arising out of the women's health,
nutritional supplements and clinical diagnostics businesses before or after the
split-off to the extent such liabilities are not otherwise retained by IMT.
Through our acquisitions of the Unipath business and IVC we also assumed or
acquired substantially all of the liabilities of those businesses. We are unable
to assess the materiality or costs associated with these lawsuits at this time.
We cannot assure you that these lawsuits or any future lawsuits relating to our
businesses will not have a material adverse effect on us.

THE PROFITABILITY OF OUR CONSUMER PRODUCTS BUSINESSES MAY SUFFER IF WE ARE
UNABLE TO ESTABLISH AND MAINTAIN CLOSE WORKING RELATIONSHIPS WITH OUR CUSTOMERS.

    Our consumer products businesses rely to a great extent on close working
relationships with our customers rather than long-term exclusive contractual
arrangements. With the exception of certain customers of IVC, customers of our
branded and private label consumer products businesses purchase products through
purchase orders only and are not obligated to make future purchases. During

                                       10

calendar year 2001, purchase orders from Walgreen Co., CVS and Rite Aid
accounted for approximately 29% of the net sales of our consumer products
businesses, excluding the Unipath businesses and IVC. The loss of major
customer, such as Walgreen, CVC or Rite Aid or the failure to generate new
accounts could dramatically reduce revenues or prevent us from achieving
projected growth.

RETAILER CONSOLIDATION POSES A THREAT TO EXISTING RETAILER RELATIONSHIPS AND CAN
RESULT IN LOST REVENUE.

    Recent years have witnessed rapid consolidation within the mass retail
industry. Drug store chains, grocery stores and mass merchandisers, the primary
purchasers of our consumer diagnostic products and vitamins and nutritional
supplements, have all been subject to this trend. Because these customers
purchase through purchase orders, consolidation can interfere with existing
retailer relationships, especially private label relationships, and result in
the loss of major customers and significant revenue streams.

OUR FINANCIAL CONDITION OR RESULTS OF OPERATIONS MAY BE ADVERSELY AFFECTED BY
INTERNATIONAL BUSINESS RISKS.

    A significant number of our employees, including sales, support and research
and development personnel, are located outside of the United States. Conducting
business outside of the United States is subject to numerous risks, including:

    - decreased liquidity resulting from longer accounts receivable collection
      cycles typical of foreign countries;

    - lower productivity resulting from difficulties managing our sales, support
      and research and development operations across many countries;

    - lost revenues resulting from difficulties associated with enforcing
      agreements and collecting receivables through foreign legal systems;

    - lost revenues resulting from the imposition by foreign governments of
      trade protection measures; and

    - higher cost of sales resulting from import or export licensing
      requirements.

BECAUSE OUR BUSINESS RELIES HEAVILY ON FOREIGN OPERATIONS AND, TO A LESSER
EXTENT, FOREIGN SALES, CHANGES IN FOREIGN CURRENCY EXCHANGE RATES AND OUR
ABILITY TO CONVERT CURRENCIES MAY NEGATIVELY AFFECT OUR FINANCIAL CONDITION AND
RESULTS OF OPERATIONS.

    Our business relies heavily on our foreign operations. Three of our
manufacturing facilities are outside the United States, in Bedford, England,
Galway, Ireland and Yavne, Israel. Orgenics has always made substantially all of
its sales outside of the United States. Through our recent acquisitions of the
Unipath business and IVC, we expect foreign sales to grow significantly. The
Unipath business generated approximately 70% of its net product sales outside of
the United States during 2001 and IVC generated almost 14% of its net product
sales outside of the United States during its fiscal year ending July 31, 2001.
Because of our foreign operations and foreign sales, we face exposure to
movements in foreign currency exchange rates. Our primary exposures are related
to the operations of our European and South American subsidiaries. These
exposures may change over time as business practices evolve and could result in
increased costs or reduced revenue and could impact actual cash flow.

                                       11

OUR ORGENICS SUBSIDIARY IS LOCATED IN ISRAEL, AND ITS OPERATIONS COULD BE
NEGATIVELY AFFECTED DUE TO MILITARY OR POLITICAL TENSIONS IN THE MIDDLE EAST.

    Our wholly-owned subsidiary, Orgenics Ltd., which develops, manufactures and
sells certain of our clinical diagnostic products, is incorporated under the
laws of the State of Israel. The administrative offices and development and
manufacturing operations of our Orgenics business are located in Yavne, Israel.
Although most of Orgenics' sales currently are to customers outside of Israel,
political, economic and military conditions in Israel could nevertheless
directly affect its operations. Since the establishment of the State of Israel
in 1948, a number of armed conflicts have taken place between Israel and its
Arab neighbors and a state of hostility, varying in degree and intensity, has
led to security and economic problems for Israel. Despite its history of
avoiding adverse effects, our Orgenics business could be adversely affected by
any major hostilities involving Israel, including the current armed conflict
with the Palestinian authority.

INTENSE COMPETITION COULD REDUCE OUR MARKET SHARE OR LIMIT OUR ABILITY TO
INCREASE MARKET SHARE, WHICH COULD IMPAIR THE SALES OF OUR PRODUCTS AND HARM OUR
FINANCIAL PERFORMANCE.

    The medical products industry is rapidly evolving and developments are
expected to continue at a rapid pace. Competition in this industry, which
includes both our consumer diagnostics and clinical diagnostics businesses, is
intense and expected to increase as new products and technologies become
available and new competitors enter the market. Our competitors in the United
States and abroad are numerous and include, among others, diagnostic testing and
medical products companies, universities and other research institutions. Our
future success depends upon our maintaining a competitive position in the
development of products and technologies in our areas of focus. Competitors may
be more successful in:

    - developing technologies and products that are more effective than our
      products or that render our technologies or products obsolete or
      noncompetitive;

    - obtaining patent protection or other intellectual property rights that
      would prevent us from developing our potential products; or

    - obtaining regulatory approval for the commercialization of their products
      more rapidly or effectively than we are in doing so.

Also, the possibility of patent disputes with competitors holding foreign patent
rights may limit or delay expansion possibilities for our consumer diagnostics
business in certain foreign jurisdictions. In addition, many of our existing or
potential competitors have or may have substantially greater research and
development capabilities, clinical, manufacturing, regulatory and marketing
experience and financial and managerial resources.

    The market for the sale of vitamins and nutritional supplements is also
highly competitive. This competition is based principally upon price, quality of
products, customer service and marketing support. There are numerous companies
in the vitamins and nutritional supplements industry selling products to
retailers such as mass merchandisers, drug store chains, independent drug
stores, supermarkets and health food stores. As most of these companies are
privately held, we are unable to obtain the information necessary to assess
precisely the size and success of these competitors. However, we believe that a
number of our competitors, particularly manufacturers of nationally advertised
brand name products, are substantially larger than we are and have greater
financial resources.

                                       12

THE RIGHTS WE RELY UPON TO PROTECT THE INTELLECTUAL PROPERTY UNDERLYING OUR
PRODUCTS MAY NOT BE ADEQUATE, WHICH COULD ENABLE THIRD PARTIES TO USE OUR
TECHNOLOGY AND WOULD REDUCE OUR ABILITY TO COMPETE IN THE MARKET.

    Our success will depend in part on our ability to develop or acquire
commercially valuable patent rights and to protect our intellectual property.
Our patent position is generally uncertain and involves complex legal and
factual questions. The degree of future protection for our proprietary rights is
uncertain.

    The risks and uncertainties that we face with respect to our patents and
other proprietary rights include the following:

    - the pending patent applications we have filed or to which we have
      exclusive rights may not result in issued patents or may take longer than
      we expect to result in issued patents;

    - the claims of any patents which are issued may not provide meaningful
      protection;

    - we may not be able to develop additional proprietary technologies that are
      patentable;

    - the patents licensed or issued to us or our customers may not provide a
      competitive advantage;

    - other companies may challenge patents licensed or issued to us or our
      customers;

    - patents issued to other companies may harm our ability to do business; and

    - other companies may design around technologies we have licensed or
      developed.

    In addition to patents, we rely on a combination of trade secrets,
nondisclosure agreements and other contractual provisions and technical measures
to protect our intellectual property rights. Nevertheless, these measures may
not be adequate to safeguard the technology underlying our products. If they do
not protect our rights, third parties could use our technology and our ability
to compete in the market would be reduced. In addition, employees, consultants
and others who participate in the development of our products may breach their
agreements with us regarding our intellectual property and we may not have
adequate remedies for the breach. We also may not be able to effectively protect
our intellectual property rights in some foreign countries. For a variety of
reasons, we may decide not to file for patent, copyright or trademark protection
or prosecute potential infringements of our patents. We also realize that our
trade secrets may become known through other means not currently foreseen by us.
Despite our efforts to protect our intellectual property, our competitors or
customers may independently develop similar or alternative technologies or
products that are equal or superior to our technology and products without
infringing on any of our intellectual property rights or design around our
proprietary technologies.

CLAIMS BY OTHER COMPANIES THAT OUR PRODUCTS INFRINGE ON THEIR PROPRIETARY RIGHTS
COULD ADVERSELY AFFECT OUR ABILITY TO SELL OUR PRODUCTS AND INCREASE OUR COSTS.

    Substantial litigation over intellectual property rights exists in both the
consumer and clinical diagnostic industries. We expect that our products and
products in these industries may increasingly be subject to third party
infringement claims as the number of competitors grows and the functionality of
products and technology in different industry segments overlaps. Third parties
may currently have, or may eventually be issued, patents on which our products
or technology may infringe. Any of these third parties might make a claim of
infringement against us. Any litigation could result in the expenditure of
significant financial resources and the diversion of management's time and
resources. In addition, litigation in which we are accused of infringement may
cause negative publicity, have an impact on prospective customers, cause product
shipment delays, require us to develop non-infringing technology or enter into
royalty or license agreements, which may not be available on acceptable terms,
or at all. If a successful claim of infringement were made against us and we
could not develop non-infringing

                                       13

technology or license the infringed or similar technology on a timely and
cost-effective basis, our revenue may decrease and we could be exposed to legal
actions by our customers.

WE HAVE INITIATED, AND MAY NEED TO FURTHER INITIATE, LAWSUITS TO PROTECT OR
ENFORCE OUR PATENTS AND OTHER INTELLECTUAL PROPERTY RIGHTS, WHICH COULD BE
EXPENSIVE AND, IF WE LOSE, COULD CAUSE US TO LOSE SOME OF OUR INTELLECTUAL
PROPERTY RIGHTS, WHICH WOULD REDUCE OUR ABILITY TO COMPETE IN THE MARKET.

    We rely on patents to protect a portion of our intellectual property and our
competitive position. In order to protect or enforce our patent rights, we may
initiate patent litigation against third parties, such as infringement suits or
interference proceedings. Litigation may be necessary to:

    - assert claims of infringement;

    - enforce our patents;

    - protect our trade secrets or know-how; or

    - determine the enforceability, scope and validity of the proprietary rights
      of others.

Currently, we have initiated a number of lawsuits against competitors who we
believe to be selling products that infringe our proprietary rights. These
current lawsuits and any other lawsuits that we initiate could be expensive,
take significant time and divert management's attention from other business
concerns. Litigation also puts our patents at risk of being invalidated or
interpreted narrowly and our patent applications at risk of not issuing.
Additionally, we may provoke third parties to assert claims against us. Patent
law relating to the scope of claims in the technology fields in which we operate
is still evolving and, consequently, patent positions in our industry are
generally uncertain. We may not prevail in any of these suits and the damages or
other remedies awarded, if any, may not be commercially valuable. During the
course of these suits, there may be public announcements of the results of
hearings, motions and other interim proceedings or developments in the
litigation. If securities analysts or investors perceive any of these results to
be negative, our stock price could decline.

WE MAY BE UNABLE TO HIRE, RETAIN OR MOTIVATE KEY PERSONNEL, UPON WHOM THE
SUCCESS OF OUR BUSINESS WILL DEPEND.

    We are highly dependent upon certain members of our management and
scientific staff, particularly Ron Zwanziger, David Scott and Jerry McAleer. We
believe that our future success will depend in large part upon our ability to
attract and retain highly skilled scientific, managerial and marketing
personnel. We face significant competition for such personnel from other
companies, research and academic institutions, government entities and other
organizations. We may fail to retain our key employees. Further, we may fail to
attract, assimilate, retain or train other needed qualified employees in the
future. We do not have employment agreements with all of our key employees. The
loss of any of our key employees, including our scientists, may impact or
disrupt our sales and marketing activities, our research and development
efforts, our capital-raising efforts or our administrative functions.

WE MAY BE LIABLE FOR CONTAMINATION OR OTHER HARM CAUSED BY HAZARDOUS MATERIALS
THAT WE USE.

    Our research and development processes involve the use of hazardous
materials. We are subject to federal, state and local regulation governing the
use, manufacture, handling, storage and disposal of hazardous materials. We
cannot completely eliminate the risk of contamination or injury resulting from
hazardous materials and we may incur liability as a result of any contamination
or injury. We may also incur expenses relating to compliance with environmental
laws. Such expenses or liability could have a significant negative impact on our
financial condition.

                                       14

OUR OPERATING RESULTS MAY FLUCTUATE DUE TO VARIOUS FACTORS AND AS A RESULT
PERIOD-TO-PERIOD COMPARISONS OF OUR RESULTS OF OPERATIONS WILL NOT NECESSARILY
BE MEANINGFUL.

    Factors relating to our business make our future operating results uncertain
and may cause them to fluctuate from period to period. Such factors include:

    - the timing of new product announcements and introductions by us and our
      competitors;

    - market acceptance of new or enhanced versions of our products;

    - changes in manufacturing costs or other expenses;

    - competitive pricing pressures;

    - the gain or loss of significant distribution outlets or customers;

    - the availability and extent of reimbursement for our products;

    - increased research and development expenses;

    - the timing of any future acquisitions;

    - general economic conditions; or

    - general stock market conditions, other economic or external factors.

THE HOLDERS OF OUR SERIES A CONVERTIBLE PREFERRED STOCK ARE ENTITLED TO RECEIVE
LIQUIDATION PAYMENTS IN PREFERENCE TO THE HOLDERS OF OUR COMMON STOCK.

    As of March 25, 2002, there were 2,360,246 shares of Series A Convertible
Preferred Stock outstanding. Pursuant to the terms of the certificate of
designation creating the Series A Convertible Preferred Stock, upon a
liquidation or a deemed liquidation of our company, the holders of the shares of
our Series A Convertible Preferred Stock are entitled to receive a liquidation
payment prior to the payment of any amount with respect to the shares of our
common stock. The amount of this preferential liquidation payment is $30 per
share of Series A Convertible Preferred Stock (or $40.50 per share in certain
circumstances), plus the amount of any dividends that have accrued on those
shares, subject to adjustment in the event of any stock dividend, stock split,
combination or other similar recapitalization affecting our Series A Convertible
Preferred Stock. Dividends accrue on the shares of our Series A Convertible
Preferred Stock at the rate of up to $2.10 per share per annum based on the
percentage of trading days on which the closing market price of our common stock
is less than $15.00. As a result of these terms, the holders of our common stock
may be disproportionately affected by any reduction in the value of our assets
or fluctuations in the market price of our common stock.

THE ABILITY OF OUR STOCKHOLDERS TO CONTROL OUR POLICIES AND EFFECT A CHANGE OF
CONTROL OF OUR COMPANY IS LIMITED, WHICH MAY NOT BE IN YOUR BEST INTERESTS.

    There are provisions in our certificate of incorporation and by-laws which
may discourage a third party from making a proposal to acquire us, even if some
of our stockholders might consider the proposal to be in their best interests.
These provisions include the following:

    - our certificate of incorporation provides for three classes of directors
      with the term of office of one class expiring each year, commonly referred
      to as a staggered board. By preventing stockholders from voting on the
      election of more than one class of directors at any annual meeting of
      stockholders, this provision may have the effect of keeping the current
      members of our board of directors in control for a longer period of time
      than stockholders may desire; and

                                       15

    - our certificate of incorporation authorizes our board of directors to
      issue shares of preferred stock without stockholder approval and to
      establish the preferences and rights of any preferred stock issued, which
      would allow the board to issue one or more classes or series of preferred
      stock that could discourage or delay a tender offer or change in control.

Additionally, we are subject to Section 203 of the Delaware General Corporation
Law, which, in general, imposes restrictions upon acquirors of 15% or more of
our stock. Finally, the board of directors may in the future adopt a shareholder
rights plan, which could delay, deter or prevent a change of control.

BECAUSE WE DO NOT INTEND TO PAY DIVIDENDS, YOU WILL BENEFIT FROM AN INVESTMENT
IN OUR COMMON STOCK ONLY IF IT APPRECIATES IN VALUE.

    We currently intend to retain our future earnings, if any, to finance the
expansion of our business and do not expect to pay any cash dividends in the
foreseeable future. As a result, the success of your investment in our common
stock will depend entirely upon any future appreciation. There is no guarantee
that our common stock will appreciate in value after the offering or even
maintain the price at which you purchased your shares.

             SPECIAL STATEMENT REGARDING FORWARD-LOOKING STATEMENTS

    This prospectus contains forward-looking statements within the meaning of
Section 27A of the Securities Act of 1933, as amended, and Section 21E of the
Securities Exchange Act of 1934, as amended. You can identify these statements
by forward-looking words such as "may," "could," "should," "would," "intend,"
"will," "expect," "anticipate," "believe," "estimate," "continue" or similar
words. You should read statements that contain these words carefully because
they discuss our future expectations, contain projections of our future results
of operations or of our financial condition or state other "forward-looking"
information. There may be events in the future that we are not able to predict
accurately or control and that may cause our actual results to differ materially
from the expectations we describe in our forward-looking statements. We caution
investors that all forward-looking statements involve risks and uncertainties,
and actual results may differ materially from those we discuss in this
prospectus. These differences may be the result of various factors, including
those factors described in the "Risk Factors" section of this prospectus. Some
important additional factors that could cause our actual results to differ
materially from those projected in any such forward-looking statements are as
follows:

    - economic factors, including inflation and fluctuations in interest rates
      and foreign currency exchange rates, and the potential effect of such
      fluctuations on revenues, expenses and resulting margins;

    - competitive factors, including technological advances achieved and patents
      attained by competitors and generic competition;

    - domestic and foreign healthcare changes resulting in pricing pressures,
      including the continued consolidation among healthcare providers, trends
      toward managed care and healthcare cost containment and government laws
      and regulations relating to sales and promotion, reimbursement and pricing
      generally;

    - government laws and regulations affecting domestic and foreign operations,
      including those relating to trade, monetary and fiscal policies, taxes,
      price controls, regulatory approval of new products and licensing;

    - manufacturing interruptions, delays or capacity constraints or lack of
      availability of alternative sources for components for our products;

    - difficulties inherent in product development, including the potential
      inability to successfully continue technological innovation, complete
      clinical trials, obtain regulatory approvals in the United States and
      abroad, gain and maintain market approval of products and the possibility
      of encountering infringement claims by competitors with respect to patent
      or other intellectual property rights which can preclude or delay
      commercialization of a product;

    - significant litigation adverse to us including product liability claims,
      patent infringement claims and antitrust claims;

    - product efficacy or safety concerns resulting in product recalls or
      declining sales;

    - the impact of business combinations, including acquisitions and
      divestitures, and organizational restructuring consistent with evolving
      business strategies;

    - our ability to satisfy the financial covenants and other conditions
      contained in our credit facilities;

    - our ability to obtain required financing on terms that are acceptable to
      us; and

    - the issuance of new or revised accounting standards by the American
      Institute of Certified Public Accountants, the Financial Accounting
      Standards Board or the Securities and Exchange Commission.

    The foregoing list sets forth many, but not all, of the factors that could
impact upon our ability to achieve results described in any forward-looking
statements. Readers should not place undue reliance on our forward-looking
statements. Before you invest in our common stock, you should be aware that the
occurrence of the events described in the "Risk Factors" section and elsewhere
in this prospectus could harm our business, prospects, operating results and
financial condition. We do not undertake any obligation to update any
forward-looking statements as a result of future events or developments.

                                       17

                REGISTRATION RIGHTS OF THE SELLING STOCKHOLDERS

    We are filing this registration statement pursuant to the terms of
registration rights granted to the selling stockholders in connection with
certain capital raising transactions, described below, used to help finance our
acquisition of the Unipath business. We acquired the Unipath business on
December 20, 2001.

    On December 20, 2001, we sold 1,995,000 shares of Series A Convertible
Preferred Stock to private investors, including certain of our directors and
related persons, at a purchase price of $30.00 per share for aggregate
consideration of $59.85 million. The Series A Convertible Preferred Stock is
currently convertible into common stock at a 2-for-1 ratio. In March 2002,
166,667 of these shares of Series A Convertible Preferred Stock were converted
into 333,334 shares of common stock. Accordingly, the 1,828,333 of these shares
of Series A Convertible Preferred Stock that remain outstanding are currently
convertible into 3,656,666 shares of common stock. Under the terms of the
related securities purchase agreement, we agreed to file the registration
statement of which this prospectus is a part to register the sale by those
investors of the shares of common stock underlying the shares of Series A
Convertible Preferred Stock acquired by them. We also agreed to use our best
efforts to cause the registration statement to be declared effective by the
Securities and Exchange Commission by June 20, 2002, and to keep the
registration statement effective until the earliest of (1) December 20, 2003,
(2) the date on which the investors may sell their shares within a three-month
period in accordance with Rule 144(k) and (3) such time as all of such shares
have been sold pursuant to a registration statement.

    On December 20, 2001, we sold subordinated promissory notes and warrants to
private investors, including Zwanziger Family Ventures, LLC, an entity
affiliated with Ron Zwanziger, our Chairman, President and Chief Executive
Officer, for an aggregate purchase price of $20.0 million. The notes were
subsequently retired using the proceeds from the sale of additional shares of
Series A Convertible Preferred Stock, as discussed below. The warrants, however,
are still outstanding and are exercisable for an aggregate of 55,189 shares of
common stock at an exercise price of $18.12 per share. Under the terms of the
related note and warrant purchase agreement, in connection with the filing of
the registration statement of which this prospectus is a part, we agreed to use
our reasonable best efforts to register the sale by the warrant holders of the
shares of common stock issuable upon exercise of their warrants.

    On December 20, 2001, we obtained a mezzanine credit facility from RBS
Mezzanine Limited for an aggregate principal amount of up to $10.0 million. In
connection with the provision of this facility, we issued to RBS Mezzanine
Limited a warrant to purchase 65,000 shares of common stock at an exercise price
of $0.001 per share. Under the terms of the warrant agreement, in connection
with the filing of the registration statement of which this prospectus is a
part, we agreed to use our reasonable best efforts to register the sale by RBS
Mezzanine Limited of the shares of common stock issuable upon exercise of this
warrant.

    As a condition to our obtaining the mezzanine credit facility, RBS Mezzanine
Limited required Zwanziger Family Ventures, LLC to enter into a lock-up
agreement pursuant to which it agreed not to sell or transfer shares of common
stock for a three-year period (subject to continuing volume limitations after
such period). In consideration of such agreement, we issued to Zwanziger Family
Ventures, LLC a warrant to purchase 385,000 shares of common stock at an
exercise price of $17.15 per share. Under the terms of the warrant agreement, in
connection with the filing of the registration statement of which this
prospectus is a part, we agreed to use our reasonable best efforts to register
the sale by Zwanziger Family Ventures, LLC of the shares of common stock
issuable upon exercise of this warrant.

    In addition, on March 6, 2002, we sold an additional 531,913 shares of
Series A Convertible Preferred Stock to private investors at a purchase price of
$39.01 per share for an aggregate consideration of $20.75 million. The proceeds
from the sale of these shares were used primarily to retire the subordinated
promissory notes issued on December 20, 2001. These shares of Series A
Convertible Preferred Stock are currently convertible into 1,063,826 shares of
common stock. The investors purchasing these shares of Series A Convertible
Preferred Stock have the same registration rights as the investors who purchased
shares of Series A Convertible Preferred Stock on December 20, 2001.

                                USE OF PROCEEDS

    We will not receive any proceeds from the sale by the selling stockholders
of the common stock covered by this prospectus. We will, however, receive the
proceeds from the exercise of the warrants, if and when exercised by selling
stockholders holding warrants. If those selling stockholders exercise in full
their respective warrants covering an aggregate of 506,412 shares of common
stock, we estimate that our net proceeds would be approximately $7,617,442. We
expect to use substantially all of the net proceeds from the exercise of the
warrants for working capital and other general corporate purposes.

                                       21

                              PLAN OF DISTRIBUTION

    The selling stockholders, or their pledgees, donees, transferees, or any of
their successors in interest, may sell the securities from time to time on the
American Stock Exchange or any other stock exchange or automated interdealer
quotation system on which the securities are listed, in the over-the-counter
market, in privately negotiated transactions or otherwise, at fixed prices that
may be changed, at market prices prevailing at the time of sale, at prices
related to prevailing market prices or at prices otherwise negotiated. The
"selling stockholders" as used in this section of the prospectus shall refer to
the selling stockholders, or their pledgees, donees, transferees, or any of
their successors in interest. The selling stockholders may sell the securities
by one or more of the following methods, without limitation:

    (a) block trades in which the broker or dealer so engaged will attempt to
       sell the securities as agent but may position and resell a portion of the
       block as principal to facilitate the transaction;

    (b) purchases by a broker or dealer as principal and resale by the broker or
       dealer for its own account pursuant to this prospectus;

    (c) a special offering, an exchange distribution or a secondary distribution
       in accordance with the rules of any stock exchange on which the
       securities are listed;

    (d) ordinary brokerage transactions and transactions in which the broker
       solicits purchases;

    (e) privately negotiated transactions;

    (f) short sales;

    (g) through the writing of options on the securities, whether or not the
       options are listed on an options exchange;

    (h) through the distribution of the securities by any selling stockholder to
       its partners, members or stockholders;

    (i) one or more underwritten offerings on a firm commitment or best efforts
       basis;

    (j) sales at other than a fixed price to or through a market maker or into
       an existing trading market, on an exchange or otherwise, for such
       securities;

    (k) through agreements between a broker or dealer and one or more of the
       selling stockholders to sell a specified number of the securities at a
       stipulated price per share; and

    (l) any combination of any of these methods of sale.

    The selling stockholders may also transfer the securities by gift. We do not
know of any arrangements by the selling stockholders for the sale of any of the
securities.

    The selling stockholders may arrange for other brokers or dealers to
participate in effecting sales of the securities. These brokers, dealers or
underwriters may act as principals or agents of a selling stockholder.
Broker-dealers may agree with a selling stockholder to sell a specified number
of the securities at a stipulated price per security. If the broker-dealer is
unable to sell securities acting as agent for a selling stockholder, it may
purchase as principal any unsold securities at the stipulated price.
Broker-dealers who acquire securities as principals may thereafter resell the
securities from time to time in transactions in any stock exchange or automated
interdealer quotation system on which the securities are then listed, at prices
and on terms then prevailing at the time of sale, at prices related to the
then-current market price or in negotiated transactions. Broker-dealers may use
block transactions and sales to and through broker-dealers, including
transactions of the nature described above. Broker-dealers will receive
commissions or other compensation from the selling stockholders in amounts to be
negotiated immediately prior to the sale that will not exceed those customary in
the types of transactions involved. Broker-dealers may also receive compensation
from purchasers of the securities which is not expected to exceed that customary
in the types of transactions involved. The selling

                                       22

stockholders may also sell the securities in accordance with Rule 144 under the
Securities Act of 1933, as amended, rather than pursuant to this prospectus,
regardless of whether the securities are covered by this prospectus.

    From time to time, one or more of the selling stockholders may pledge,
hypothecate or grant a security interest in some or all of the securities owned
by them. The pledgees, secured parties or persons to whom the securities have
been hypothecated will, upon foreclosure in the event of default, be deemed to
be selling stockholders. The number of a selling stockholder's securities
offered under this prospectus will decrease as and when it takes such actions.
The plan of distribution for that selling stockholder's securities will
otherwise remain unchanged. In addition, a selling stockholder may, from time to
time, sell the securities short, and, in those instances, this prospectus may be
delivered in connection with the short sales and the securities offered under
this prospectus may be used to cover short sales.

    To the extent required under the Securities Act of 1933, the aggregate
amount of selling stockholders' securities being offered and the terms of the
offering, the names of any agents, brokers, dealers or underwriters and any
applicable commission with respect to a particular offer will be set forth in an
accompanying prospectus supplement. Any underwriters, dealers, brokers or agents
participating in the distribution of the securities may receive compensation in
the form of underwriting discounts, concessions, commissions or fees from a
selling stockholder and/or purchasers of a selling stockholder's securities, for
whom they may act (which compensation as to a particular broker-dealer might be
in excess of customary commissions).

    The selling stockholders and any underwriters, brokers, dealers or agents
that participate in the distribution of the securities may be deemed to be
"underwriters" within the meaning of the Securities Act of 1933, and any
discounts, concessions, commissions or fees received by them and any profit on
the resale of the securities sold by them may be deemed to be underwriting
discounts and commissions.

    A selling stockholder may enter into hedging transactions with
broker-dealers and the broker-dealers may engage in short sales of the
securities in the course of hedging the positions they assume with that selling
stockholder, including, without limitation, in connection with distributions of
the securities by those broker-dealers. A selling stockholder may enter into
option or other transactions with broker-dealers that involve the delivery of
the securities offered hereby to the broker-dealers, who may then resell or
otherwise transfer those securities. A selling stockholder may also loan or
pledge the securities offered hereby to a broker-dealer and the broker-dealer
may sell the securities offered hereby so loaned or upon a default may sell or
otherwise transfer the pledged securities offered hereby.

    The selling stockholders and other persons participating in the sale or
distribution of the securities will be subject to applicable provisions of the
Securities Exchange Act of 1934, as amended, and the rules and regulations
thereunder, including Regulation M. This regulation may limit the timing of
purchases and sales of any of the securities by the selling stockholders and any
other person. The anti-manipulation rules under the Securities Exchange Act of
1934 may apply to sales of securities in the market and to the activities of the
selling stockholders and their affiliates. Furthermore, Regulation M may
restrict the ability of any person engaged in the distribution of the securities
to engage in market-making activities with respect to the particular securities
being distributed for a period of up to five business days before the
distribution. These restrictions may affect the marketability of the securities
and the ability of any person or entity to engage in market-making activities
with respect to the securities.

    We have agreed to indemnify and hold harmless the selling stockholders and
each person, if any, who controls a selling stockholder within the meaning of
the Securities Act of 1933 (and, with respect to one selling stockholder, its
officers, directors and underwriters) against specified liabilities, including
liabilities under the federal securities laws. The selling stockholders have
agreed to indemnify and hold harmless us, certain directors, officers and
control persons against specified liabilities, including liabilities under the
federal securities laws.

                                       23

    The securities offered hereby were originally issued to the selling
stockholders pursuant to an exemption from the registration requirements of the
Securities Act of 1933. We agreed to register the securities under the
Securities Act of 1933. We will pay all expenses relating to the offering and
sale of the securities, with the exception of commissions, discounts and fees of
underwriters, broker-dealers or agents, taxes of any kind and any legal,
accounting and other expenses incurred by the selling stockholders.

    We will not receive any proceeds from the sale by the selling stockholders
of the common stock covered by this prospectus.

    We can not assure you that the selling stockholders will sell all or any
portion of the securities offered hereby.

    We will supply the selling stockholders and any stock exchange upon which
the securities are listed with reasonable quantities of copies of this
prospectus. To the extent required by Rule 424 under the Securities Act of 1933
in connection with any resale or redistribution by a selling stockholder, we
will file a prospectus supplement setting forth:

    - the aggregate number of shares to be sold;

    - the purchase price;

    - the public offering price;

    - if applicable, the names of any underwriter, agent or broker-dealer; and

    - any applicable commissions, discounts, concessions, fees or other items
      constituting compensation to underwriters, agents or broker-dealers with
      respect to the particular transaction (which may exceed customary
      commissions or compensation).

If a selling stockholder notifies us that a material arrangement has been
entered into with a broker-dealer for the sale of shares through a block trade,
special offering, exchange, distribution or secondary distribution or a purchase
by a broker or dealer, the prospectus supplement will include any other facts
that are material to the transaction. If applicable, this may include a
statement to the effect that the participating broker-dealers did not conduct
any investigation to verify the information set out or incorporated by reference
in this prospectus.

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

    Section 145 of the Delaware General Corporation Law provides that a
corporation may indemnify any person who was or is a party or is threatened to
be made a party to any threatened, pending or completed action, suit or
proceeding, whether civil, criminal, administrative or investigative, other than
an action by or in the right of the corporation, by reason of the fact that the
person is or was a director, officer, employee or agent of the corporation or is
or was serving at the corporation's request as a director, officer, employee or
agent of another corporation, partnership, joint venture, trust or other
enterprise, against expenses, including attorneys' fees, judgments, fines and
amounts paid in settlement actually and reasonably incurred by the person in
connection with the action, suit or proceeding if the person acted in good faith
and in a manner the person reasonably believed to be in or not opposed to the
best interests of the corporation, and, with respect to any criminal action or
proceeding, had no reasonable cause to believe the person's conduct was
unlawful. The power to indemnify applies to actions brought by or in the right
of the corporation as well, but only to the extent of expenses, including
attorneys' fees but excluding judgments, fines and amounts paid in settlement,
actually and reasonably incurred by the person in connection with the defense or
settlement of the action or suit. And with the further limitation that in these
actions, no indemnification shall be made in the event of any adjudication of
negligence or misconduct in the performance of the person's duties to the
corporation, unless a court believes that in light of all the circumstances
indemnification should apply.

    Article V of the by-laws of Inverness Medical Innovations, Inc.
("Innovations") provides that Innovations shall, to the extent legally
permitted, indemnify each person who was or is a party or is threatened to be
made a party to any threatened, pending or completed action, suit or proceeding
by reason of the fact that such person is or was, or has agreed to become, a
director or officer of Innovations, or is or was serving, or has agreed to
serve, at the request of Innovations, as a director, officer, trustee, partner,
employee or agent of, or in a similar capacity with, another corporation,
partnership, joint venture, trust, employee benefit plan or other enterprise.
The indemnification provided for in Article V is expressly not exclusive of any
other rights to which those seeking indemnification may be entitled under any
law, agreement or vote of stockholders or disinterested directors or otherwise,
and shall inure to the benefit of the heirs, executors and administrators of
such persons.

                                      II-1

    Section 145(g) of the Delaware General Corporation Law and Article V of the
by-laws of Innovations provide that Innovations shall have the power to purchase
and maintain insurance on behalf of its officers, directors, employees and
agents, against any liability asserted against and incurred by such persons in
any such capacity.

    Innovations has obtained insurance covering its directors and officers
against losses and insuring Innovations against certain of its obligations to
indemnify its directors and officers.

    Section 102(b)(7) of the General Corporation Law of the State of Delaware
provides that a corporation may eliminate or limit the personal liability of a
director to the corporation or its stockholders for monetary damages for breach
of fiduciary duty as a director, provided that such provisions shall not
eliminate or limit the liability of a director (i) for any breach of the
director's duty of loyalty to the corporation or its stockholders, (ii) for acts
or omissions not in good faith or which involve intentional misconduct or a
knowing violation of law, (iii) under section 174 of the General Corporation Law
of the State of Delaware regarding the unlawful payment of dividends, or
(iv) for any transaction from which the director derived an improper personal
benefit. No such provision shall eliminate or limit the liability of a director
for any act or omission occurring prior to the date when such provision becomes
effective.

    Pursuant to the Delaware General Corporation Law, Article VII of the
certificate of incorporation of Innovations eliminates a director's personal
liability for monetary damages to Innovations and its stockholders for breach of
fiduciary duty as a director, except in circumstances involving a breach of the
director's duty of loyalty to Innovations or its stockholders, acts or omissions
not in good faith, intentional misconduct, knowing violations of the law,
self-dealing or the unlawful payment of dividends or repurchase of stock.

ITEM 17. UNDERTAKINGS.

A. The undersigned Registrant hereby undertakes:

1.  To file, during any period in which offers or sales are being made, a
    post-effective amendment to this Registration Statement:

    (i) To include any prospectus required by Section 10(a)(3) of the Securities
        Act;

    (ii) To reflect in the prospectus any facts or events arising after the
         effective date of the Registration Statement (or the most recent
         post-effective amendment thereof) which, individually or in the
         aggregate, represent a fundamental change in the information set forth
         in the Registration Statement. Notwithstanding the foregoing, any
         increase or decrease in volume of securities offered (if the total
         dollar value of securities offered would not exceed that which was
         registered) and any deviation from the low or high and of the estimated
         maximum offering range may be reflected in the form of prospectus filed
         with the Commission pursuant to Rule 424(b) if, in the aggregate, the
         changes in volume and price represent no more than a 20 percent change
         in the maximum aggregate offering price set forth in the "Calculation
         of Registration Fee" table in the effective registration statement.

   (iii) To include any material information with respect to the plan of
         distribution not previously disclosed in the Registration Statement or
         any material change to such information in the registration statement.

    PROVIDED, HOWEVER, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if
    the information required to be included in a post-effective amendment by
    those paragraphs is contained in periodic reports filed with or furnished to
    the Securities and Exchange Commission by the undersigned registrant
    pursuant to Section 13 or 15(d) of the Securities Exchange Act of 1934 that
    are incorporated by reference in the registration statement.

                                      II-3

2.  That, for the purpose of determining any liability under the Securities Act
    of 1933, each such post-effective amendment shall be deemed to be a new
    registration statement relating to the securities offered therein, and the
    offering of such securities at that time to be the initial BONA FIDE
    offering thereof.

3.  To remove from registration by means of a post-effective amendment any of
    the securities being registered which remain unsold at the termination of
    the offering.

4.  The undersigned registrant hereby undertakes that, for purposes of
    determining any liability under the Securities Act of 1933, each filing of
    the undersigned registrant's annual report pursuant to Section 13(a) or
    15(d) of the Securities Exchange Act of 1934 (and, where applicable, each
    filing of an employee benefit plan's annual report pursuant to
    Section 15(d) of the Securities Exchange Act of 1934) that is incorporated
    by reference in the registration statement shall be deemed to be a new
    registration statement relating to the securities offered therein, and the
    offering of such securities at that time shall be deemed to be the initial
    BONA FIDE offering hereof.

5.  Insofar as indemnification for liabilities arising under the Securities Act
    of 1933, may be permitted to directors, officers and controlling persons of
    the undersigned registrant pursuant to the foregoing provisions, or
    otherwise, the undersigned registrant has been advised that in the opinion
    of the Securities and Exchange Commission such indemnification is against
    public policy as expressed in the Act and is, therefore, unenforceable. In
    the event that a claim for indemnification against such liabilities (other
    than the payment by the undersigned registrant of expenses incurred or paid
    by a director, officer or controlling person of the undersigned registrant
    in the successful defense of any action, suit or proceeding) is asserted by
    such director, officer or controlling person in connection with the
    securities being registered, the undersigned registrant will, unless in the
    opinion of its counsel the matter has been settled by controlling precedent,
    submit to a court of appropriate jurisdiction the question whether such
    indemnification by it is against public policy as expressed in the Act and
    will be governed by the final adjudication of such issue.

                                      II-4

                                   SIGNATURES

    Pursuant to the requirements of the Securities Act of 1933, the registrant
certifies that it has reasonable grounds to believe that it meets all of the
requirements for filing on Form S-3 and has duly caused this registration
statement to be signed on its behalf by the undersigned, thereunto duly
authorized, in the city of Waltham, Commonwealth of Massachusetts, on April 5,
2002.
