This Amendment No. 1 to Schedule 13D is filed by the undersigned to amend the
disclosures contained in Items 3, 4, 5, 6 and 7 of the Schedule 13D originally
filed on December 31, 2001 by Ron Zwanziger, Janet Zwanziger and Zwanziger
Family Ventures, LLC (the "Schedule 13D"). Unless specifically amended hereby,
the disclosure set forth in the Schedule 13D shall remain unchanged. Capitalized
terms used but not expressly defined herein shall have the meaning ascribed to
them in the Schedule 13D.

ITEM 3. SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION.

        On November 21, 2001, pursuant to an Agreement and Plan of Split-Off and
        Merger dated as of May 23, 2001 (the "Split-Off and Merger Agreement"),
        Johnson & Johnson acquired Inverness Medical Technology, Inc. ("IMT") in
        a merger transaction and, simultaneously, Inverness Medical Innovations,
        Inc. ("Innovations"), formerly a majority-owned subsidiary of IMT, was
        split off from IMT as a separate, publicly-traded company (the
        "Split-Off and Merger"). At the effective time of the Split-Off and
        Merger, the outstanding shares of IMT common stock were converted into
        rights to receive shares of Johnson & Johnson common stock and shares of
        Innovations common stock, and the outstanding options and warrants to
        purchase shares of IMT common stock were converted into options and
        warrants to purchase shares of Johnson & Johnson common stock and
        options and warrants to purchase shares of Innovations common stock.

        As a result of the conversions described above in connection with the
        Split-Off and Merger, Ron Zwanziger acquired an aggregate of 14,450
        shares of Innovations common stock and options to purchase an aggregate
        of 282,485 shares of Innovations common stock, Janet M. Zwanziger
        acquired an aggregate of 2,600 shares of Innovations common stock, and
        Family Ventures acquired an aggregate of 117,428 shares of Innovations
        common stock.

        Pursuant to a Restricted Stock Agreement dated as of August 15, 2001
        (the "Restricted Stock Agreement") between Ron Zwanziger and
        Innovations, Ron Zwanziger purchased 152.741423722644 shares of
        Innovations common stock for aggregate consideration consisting of cash
        in the amount of $.15 and a Promissory Note dated August 16, 2001 (the
        "Promissory Note") in the principal amount of $10,655,583.68 made by Mr.
        Zwanziger in favor of Innovations. The cash portion of the purchase
        price was paid with Mr. Zwanziger's personal funds. Copies of the
        Restricted Stock Agreement and the Promissory Note are filed as EXHIBIT
        1 and EXHIBIT 2, respectively, to the Schedule 13D and are incorporated
        herein by reference. Immediately prior to the consummation of the
        Split-Off and Merger, Innovations effected a stock split with respect to
        the Innovations common stock (the "Stock Split"); as a result of the
        Stock Split, the 152.741423722644 shares of Innovations common stock
        owned by Mr. Zwanziger before giving effect to the Stock Split became
        1,168,191 shares of Innovations common stock. See Item 6 below for
        additional description of the terms of the Restricted Stock Agreement
        and the Promissory Note.

        On December 20, 2001, Family Ventures purchased 500,000 shares of Series
        A Convertible Preferred Stock, par value $.001 per share, of Innovations
        (the "Series A Preferred Stock") for a purchase price per share of $30
        in cash and an aggregate purchase price of $15,000,000 in cash. As of
        the date of this Schedule 13D/A, each share of Series A Preferred Stock
        is convertible into two shares of Innovations common stock, and the
        500,000 shares of Series A Preferred Stock beneficially owned by Family
        Ventures are convertible into 1,000,000 shares of Innovations common
        stock in the aggregate. The conversion rate is subject to adjustment
        upon certain dilutive equity issuances by Innovations and events such as
        stock splits, stock dividends and the like with respect to the
        Innovations common stock. The source of funds for these purchases
        consisted of cash contributed by one of the members of Family Ventures
        and cash realized upon the sale of certain securities by Family
        Ventures.

        On December 20, 2001, Family Ventures purchased from Innovations a
        subordinated promissory note in the principal amount of $10,000,000 (the
        "Subordinated Note") and a warrant representing the right to purchase
        27,594 shares of Innovations common stock; the aggregate consideration
        paid by Family Ventures for such purchase consisted of cash in the
        amount of $10,000,000. The source of funds for these purchases consisted
        of cash contributed by one of the members of Family Ventures and cash
        realized upon the sale of certain securities by Family Ventures. The
        subordinated promissory note was repaid in full in cash by Innovations
        on March 6, 2002.

        On December 20, 2001, Innovations granted to Ron Zwanziger a
        non-qualified employee stock option under the terms of Innovations' 2001
        Stock Option and Incentive Plan for the purchase of 115,000 shares of
        Innovations common stock; such grant was made in consideration of his
        entry into the Lock Up Agreement described in Item 6 below. On December
        20, 2001, Innovations granted to Family Ventures a warrant for the
        purchase of 385,000 shares of Innovations common stock; such grant was
        made in consideration of its entry into the Lock Up Agreement


                                 (Page 5 of 10)





        described in Item 6 below. Both the option and the warrant described in
        this paragraph are immediately exercisable in full.

        On December 21, 2001, Family Ventures purchased 156,263 shares of
        Innovations common stock from Zwanziger Associates, LLC, a Delaware
        limited liability company ("Zwanziger Associates"), whose managers are
        Ron Zwanziger and Janet M. Zwanziger. The aggregate consideration
        delivered by Family Ventures for such purchase was a cash payment to
        Zwanziger Associates of $1,815,267, constituting a per share purchase
        price of approximately $11.62. The source of funds for these purchases
        consisted of cash contributed by one of the members of Family Ventures
        and cash realized upon the sale of certain securities by Family
        Ventures. On March 1, 2002, Ron Zwanziger voluntarily ceded options to
        purchase 50,000 shares of Innovations common stock at a price of $17.15
        per share in consideration of an agreement by Innovations that any
        repurchases under the Restricted Stock Agreement would be at the then
        current market price rather than at cost.

        On May 28, 2002, Family Ventures purchased from Innovations, as part of
        a registered public offering conducted by Innovations, 100,000 shares of
        Innovations common stock at a purchase price per share of $23.00. The
        aggregate consideration delivered by Family Ventures for such purchase
        was a cash payment of $2,300,000. The source of funds for these
        purchases consisted of cash contributed by one of the members of Family
        Ventures.

ITEM 4. PURPOSE OF TRANSACTION.

        All of the shares of Innovations common stock beneficially owned by Ron
        Zwanziger, Janet M. Zwanziger and Family Ventures, as the case may be,
        and reported in the Schedule 13D, as amended, were acquired for
        investment purposes.

ITEM 5. INTEREST IN SECURITIES OF THE ISSUER.

        (a) Based upon information supplied by Innovations, 11,357,644 shares of
        Innovations common stock were outstanding as of May 31, 2002.

        Ron Zwanziger may be deemed to beneficially own an aggregate of
        3,319,009 shares of Innovations common stock, which constitutes 25.79%
        of such class of securities. This total includes 1,430,641 shares of
        Innovations common stock registered in the name of Mr. Zwanziger and
        options to purchase an aggregate of 99,485 additional shares of
        Innovations common stock exercisable within 60 days of the date of
        this statement on Schedule 13D/A also registered in the name of
        Mr. Zwanziger. This total also includes the 1,786,283 shares of
        Innovations common stock beneficially owned by Family Ventures as
        described below, over which Mr. Zwanziger, as a manager of Family
        Ventures, has voting and dispositive power. This total also includes
        2,600 shares of Innovations common stock owned by Mr. Zwanziger's wife,
        Janet M. Zwanziger, as to which he disclaims beneficial ownership. This
        total excludes 9,450 shares of Innovations common stock owned by a
        charitable foundation on whose board of directors Mr. Zwanziger and
        Janet M. Zwanziger, along with three others, serve as directors. Both
        Mr. Zwanziger and Janet M. Zwanziger have recused themselves from any
        discussion or consideration of the charitable foundation's disposition
        of these securities and they disclaim beneficial ownership of such
        securities. This total also excludes 100,230 shares of Innovations
        common stock held by a trust for the benefit of the family of
        Mr. Zwanziger and Janet M. Zwanziger; neither Mr. Zwanziger nor
        Janet M. Zwanziger is a trustee of such trust or has voting or
        dispositive power over such securities, and they disclaim beneficial
        ownership of such securities. Mr. Zwanziger's beneficial ownership
        percentage reported above has been calculated giving effect to the
        conversion of the 500,000 shares of Series A Preferred Stock and the
        options and warrants to purchase Innovations common stock that may be
        deemed to be beneficially owned by him and are reported in this
        Schedule 13D, as amended, and without giving effect to conversion of
        any of the other approximately 1,565,407 shares of Series A Preferred
        Stock or any other options, warrants, rights, or conversion privileges
        to purchase Innovations common stock outstanding on the date of this
        statement on Schedule 13D/A.

        Janet M. Zwanziger may be deemed to beneficially own an aggregate of
        3,319,009 shares of Innovations common stock, which constitutes 25.79%
        of such class of securities. This total includes the 1,786,283 shares of
        Innovations common stock beneficially owned by Family Ventures as
        described below, over which Ms. Zwanziger, as a manager of Family
        Ventures, has voting and dispositive power. This total also includes
        1,430,641 shares of Innovations common stock and options to purchase up
        to 99,485 additional shares of Innovations common stock exercisable
        within 60 days of the date of this statement on Schedule 13D/A that are
        registered in the name of Ms. Zwanziger's husband, Ron Zwanziger, as to
        which she disclaims beneficial ownership. Ms. Zwanziger's total
        beneficial ownership excludes 9,450 shares of Innovations common stock
        owned by a charitable foundation on whose board of directors
        Ms. Zwanziger and Ron Zwanziger along with three others serve as
        directors. Both Ms. Zwanziger and


                                 (Page 6 of 10)





        Ron Zwanziger have recused themselves from any discussion or
        consideration of the charitable foundation's disposition of these
        securities and they disclaim beneficial ownership of such securities.
        Ms. Zwanziger's total beneficial ownership also excludes 100,230 shares
        of Innovations common stock held by a trust for the benefit of the
        family of Ms. Zwanziger and Ron Zwanziger; neither Ms. Zwanziger nor Ron
        Zwanziger is a trustee of such trust or has voting or dispositive power
        over such securities, and they disclaim beneficial ownership of such
        securities. Ms. Zwanziger's beneficial ownership percentage reported
        above has been calculated giving effect to the conversion of the 500,000
        shares of Series A Preferred Stock and the options and warrants to
        purchase Innovations common stock that may be deemed to be beneficially
        owned by her and are reported in this Schedule 13D, as amended, and
        without giving effect to conversion of any of the other approximately
        1,565,407 shares of Series A Preferred Stock or any other options,
        warrants, rights, or conversion privileges to purchase Innovations
        common stock outstanding on the date of this statement on
        Schedule 13D/A.

        Family Ventures beneficially owns an aggregate of 1,786,283 shares of
        Innovations common stock, which constitutes 13.99% of such class of
        securities. This total includes an aggregate of 412,594 shares of
        Innovations common stock issuable pursuant to warrants held by Family
        Ventures to purchase shares of Innovations common stock that are
        exercisable within 60 days of the date of this statement on Schedule
        13D/A. This total includes shares of Series A Preferred Stock that may
        be converted into 1,000,000 shares of Innovations common stock within
        60 days of the date of this Schedule 13D. Family Ventures' beneficial
        ownership percentage reported above has been calculated giving effect
        to the conversion of the 500,000 shares of Series A Preferred Stock and
        the warrants to purchase Innovations common stock beneficially owned by
        it and reported in this Schedule 13D, as amended, and without giving
        effect to conversion of any of the other approximately 1,565,407 shares
        of Series A Preferred Stock or any other options, warrants, rights, or
        conversion privileges to purchase Innovations common stock outstanding
        on the date of this statement on Schedule 13D/A.

        (b) Ron Zwanziger and Janet M. Zwanziger may be deemed to share voting
        and dispositive power over all 3,319,009 shares of Innovations common
        stock reported as beneficially owned by each of them in Item 5(a) above.

        Family Ventures has sole power to vote and dispose of the 1,786,283

ITEM 6. CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH RESPECT TO
SECURITIES OF THE ISSUER.

        As described in Item 3 above, pursuant to the Restricted Stock
        Agreement, Ron Zwanziger purchased 152.741423722644 shares of
        Innovations common stock for aggregate consideration consisting of cash
        in the amount of $.15 and the delivery of the Promissory Note. Pursuant
        to a Pledge Agreement dated as of August 16, 2001 (the "Pledge
        Agreement") between Mr. Zwanziger and Innovations, Mr. Zwanziger pledged
        the shares purchased pursuant to the Restricted Stock Agreement to
        Innovations as collateral to secure his obligations under the Promissory
        Note. After giving effect to the Stock Split, the number of shares of
        Innovations common stock subject to the terms and conditions of the
        Restricted Stock Agreement, the Promissory Note and the Pledge Agreement
        consist of 1,168,191 shares of Innovations common stock (the "Subject
        Shares").

        Under the Restricted Stock Agreement, one-third of the Subject Shares
        (the "Four-Year Vesting Shares") are subject to a right of Innovations
        to repurchase unvested Subject Shares upon a termination of Mr.
        Zwanziger's employment with Innovations for any reason, including on
        account of death, disability, retirement or discharge or resignation for
        any reason, voluntary or involuntary, as described therein; the
        Four-Year Vesting Shares vest in forty-eight equal monthly installments
        commencing on November 30, 2001. Two-thirds of the Subject Shares (the
        "Three-Year Vesting Shares") are subject to a right of Innovations to
        repurchase unvested Subject Shares upon a termination of Mr. Zwanziger's
        employment with Innovations for any reason (including retirement or
        discharge or resignation for any reason), other than on account of
        death, disability, termination without cause or constructive
        termination, as described therein; the Three-Year Vesting Shares vest in
        thirty-six equal monthly installments commencing on November 30, 2001.
        Upon Mr. Zwanziger's death, disability, termination without cause or
        constructive termination


                                 (Page 7 of 10)





        as described therein, all Three-Year Vesting Shares will vest in full.
        Under the Restricted Stock Agreement the purchase price per share for
        any such repurchase of Subject Shares by Innovations was to be the
        purchase price per share paid by Mr. Zwanziger for the Subject Shares so
        repurchased. However, as of March 1, 2002 Innovations agreed, in
        consideration of Mr. Zwanziger ceding options to purchase 50,000 shares
        of Innovations common stock, to repurchase shares pursuant to the
        Restricted Stock Agreement at the market price of its common stock on
        the date of Mr. Zwanziger's termination rather than at Mr. Zwanziger's
        cost.

        Mr. Zwanziger may not sell, pledge or otherwise transfer or dispose of
        any Subject Shares that have not vested as described above, except to
        certain of his family members, any trust for their benefit, any family
        limited partnership or family limited liability company of which the
        limited partners or members, as the case may be, consist solely of such
        family members, and the estate, heirs and distibutees of Mr. Zwanziger
        or any such permitted transferee.

        The principal amount of the Promissory Note (the "Principal") is due and
        payable on August 16, 2006, and interest on the unpaid balance of the
        Principal accrues at the rate of 4.99% per annum, compounded annually,
        and is payable on each anniversary of the date of the Promissory Note,
        commencing on August 16, 2002, and at maturity. Mr. Zwanziger is also
        obligated to pay the Principal and accrued interest thereon with the net
        after-tax proceeds of any sale by him of any of the Subject Shares. Mr.
        Zwanziger may also pay all or part of the Principal and accrued interest
        thereon by delivering shares of the Innovations common stock held by Mr.
        Zwanziger to Innovations for their fair market value at the time of
        delivery, provided that the principal balance and interest owed under
        any promissory note used to purchase such shares or secured in whole or
        in part by such shares have been paid. Under the Promissory Note,
        Innovations shall have recourse against (i) any assets of Mr. Zwanziger
        up to (A) twenty-five percent (25%) of the Principal reduced by
        twenty-five percent (25%) of each payment of Principal made by the Mr.
        Zwanziger and (B) the full amount of accrued interest on the Principal
        and (ii) the Restricted Shares, which have been pledged pursuant to the
        Pledge Agreement. The Promissory Note was made by Mr. Zwanziger in favor
        of Innovations in replacement of the full recourse promissory note dated
        August 15, 2001 in the same principal amount made by Mr. Zwanziger in
        favor of Innovations and referred to in the Restricted Stock Agreement.
        Copies of the Restricted Stock Agreement, the Promissory Note and the
        Pledge Agreement are attached to the Schedule 13D, as amended, as
        EXHIBIT 1, EXHIBIT 2 and EXHIBIT 3, respectively, and are incorporated
        herein by reference. The descriptions in the Schedule 13D, as amended,
        of the Restricted Stock Agreement, the Promissory Note, the Pledge
        Agreement and the transactions contemplated thereby do not purport to
        be complete and are qualified in their entirety by reference to such
        exhibits.

        In connection with Innovations' entry into a Mezzanine Loan Agreement
        dated December 20, 2001 (the "Mezzanine Loan Agreement") with Inverness
        Medical Switzerland GmbH, RBS Mezzanine Limited ("RBS") as arranger and
        agent, and certain banks and other parties, Mr. Zwanziger and Family
        Ventures were required to enter into a Lock Up Agreement dated December
        20, 2001 (the "Lock Up Agreement") with RBS. Pursuant to the Lock Up
        Agreement, Mr. Zwanziger and Family Ventures agreed (i) during the
        period from December 20, 2001 through December 20, 2004, not to sell,
        pledge, transfer or otherwise dispose of (collectively, "Sell") any
        shares of Innovations common stock or any options, warrants or other
        securities exchangeable for or convertible into shares of Innovations
        common stock (collectively, "Innovations Securities") beneficially owned
        by them and (ii) during the period from December 20, 2004 through the
        date on which Innovations has made full and final payment of all amounts
        due under the Mezzanine Loan Agreement, not to Sell Innovations
        Securities representing more than an aggregate of twenty-five percent
        (25%) of the total number of shares of Innovations common stock
        represented by all of Innovations Securities beneficially owned by them
        on December 20, 2004, and not to Sell more than an aggregate of ten
        percent (10%) of such number in any twelve (12) month period, provided
        that neither Mr. Zwanziger nor Family Ventures may Sell any Innovations
        Securities at any time that Innovations is in default under the
        Mezzanine Loan Agreement. A copy of the Lock Up Agreement is attached to
        the Schedule 13D, as amended, as EXHIBIT 4 and is incorporated herein
        by reference. The description in the Schedule 13D, as amended, of the
        Lock Up Agreement and the transactions contemplated thereby does not
        purport to be complete and is qualified in its entirety by reference to
        such exhibit.

        At the date hereof, Ron Zwanziger and Janet M. Zwanziger have no formal
        arrangement with respect to the securities of Innovations, but by virtue
        of their marriage, they may coordinate decisions relating to those
        securities, including decisions in their capacities as managers of
        Family Ventures.
