Ladies and Gentlemen:

The undersigned hereby acknowledges receipt of the prospectus dated                      , 2004 (as the same may be amended and supplemented from time to time, the “prospectus”) and the related Letter of Transmittal (which together with the prospectus constitute the “exchange offer”) which describes the offer of Inverness Medical Innovations, Inc., a Delaware corporation (the “Company”) to exchange $1,000 in principal amount of 8¾% Senior Subordinated Notes due 2012 of the Company (the “new notes”) for each $1,000 in principal amount of old notes.

The undersigned hereby tenders to the Company the aggregate principal amount of old notes set forth below pursuant to the guaranteed delivery procedures and upon the terms and conditions set forth in the prospectus and the related Letter of Transmittal.

The undersigned understands that no withdrawal of a tender of old notes may be made on or after the expiration date of the exchange offer. The undersigned understands that for a withdrawal of a tender of old notes to be effective, a written notice of withdrawal that complies with the requirements of the exchange offer must be timely received by the exchange agent at its address specified on the cover of this Notice of Guaranteed Delivery prior to the expiration date.

The undersigned understands that the exchange of old notes for new notes pursuant to the exchange offer will be made only after timely receipt by the Exchange Agent of (i) such old notes (or Book-Entry Confirmation of the transfer of such old notes into the exchange agent’s account at DTC) and (ii) a Letter of Transmittal (or facsimile thereof) with respect to such old notes, properly completed and duly executed, with any required signature guarantees, this Notice of Guaranteed Delivery and any other documents required by the Letter of Transmittal or a properly transmitted Agent’s Message. The term “Agent’s Message” means, with respect to any tendered old notes, a message transmitted by DTC, received by the exchange agent and forming part of the book-entry confirmation, which states that DTC has received an express acknowledgment from each tendering participant to the effect that, with respect to those old notes they have received the Letter of Transmittal and agrees to be bound by the terms of the Letter of Transmittal and the Company may enforce such agreement against such participant.

The undersigned hereby represents, warrants and agrees that the undersigned has full power and authority to tender, exchange, sell, assign, and transfer the tendered old notes and that the Company will acquire good, marketable and unencumbered title thereto, free and clear of all liens, restrictions, charges and encumbrances when the tendered old notes are acquired by the Company as contemplated herein, and the tendered old notes are not subject to any adverse claims or proxies. The undersigned warrants and agrees that the undersigned and each beneficial owner will, upon request, execute and deliver any additional documents deemed by the Company and/or the exchange agent to be necessary or desirable to complete the tender, exchange, sale, assignment and transfer of the tendered old notes, and that the undersigned will comply with its obligations under the registration rights agreement. The undersigned has read and agreed to all of the terms of the exchange offer.

By tendering old notes and executing this Notice of Guaranteed Delivery, the undersigned hereby represents and warrants that (i) neither the undersigned nor any beneficial owner(s) is an “affiliate” of the Company, (ii) any new notes to be received by the undersigned and any beneficial owner(s) are being acquired by the undersigned and any beneficial owner(s) in the ordinary course of business of the undersigned and any beneficial owner(s), (iii) the undersigned and each beneficial owner have no arrangement or understanding with any person to participate in a distribution (within the meaning of the Securities Act) of new notes to be received in the exchange offer in violation of the provisions of the Securities Act, (iv) the undersigned is not a broker-dealer tendering old notes acquired directly from the Company and (v) the undersigned or any such beneficial owner is not engaged in, and does not intend to engage in, a distribution (within the meaning of the Securities Act) of such new notes.

2

All questions as to the form of all documents and the validity, including time of receipt, and acceptance of all tenders of old notes will by determined by the Company, in its sole discretion, whose determination shall be final and binding on all the parties. Alternative, conditional or contingent tenders of old notes will not be considered valid. The Company reserves the absolute right to reject any and all tenders of old notes that are not in proper form or the acceptance of which, in the Company’s opinion, would be unlawful.

All authority conferred or agreed to be conferred by this Notice of Guaranteed Delivery shall not be affected by, and shall survive, the death or incapacity of the undersigned, and every obligation of the undersigned under this Notice of Guaranteed Delivery shall be binding upon the heirs, executors, administrators, trustees in bankruptcy, personal and legal representatives, successors and assigns of the undersigned.
