Chembio Submits CLIA Waiver Data for HIV Barrel Test to FDA

Waiver Would Greatly Expand U.S. Market Potential of FDA-Approved Test

MEDFORD, NY--(Marketwire - August 14, 2007) - Chembio Diagnostics, Inc. (OTCBB: CEMI) has completed the studies required as part of a Clinical Laboratory Improvement Amendment (CLIA) waiver application for its "HIV barrel format" rapid test. Chembio has submitted this data and associated information in an amendment to its 2006 submission to the Center for Devices and Radiological Health division of the United States Food & Drug Administration (FDA). If the CLIA waiver is granted, it would expand the available market for Chembio's HIV barrel format test to include doctors' offices and clinics, as well as other hospitals and reference laboratories. This unique, self-contained rapid HIV test is FDA approved and exclusively marketed worldwide by Inverness Medical Innovations, Inc. as Clearview® COMPLETE HIV 1/2.

The Clinical Laboratory Improvement Amendments of 1988 (CLIA) established that some tests could be waived from certain laboratory requirements. Waived products include tests that employ methodologies that are so simple to use as to render the likelihood of erroneous results negligible; or that pose no reasonable risk of harm to the patient if the test is performed incorrectly. Rapid HIV antibody tests were only added to the list of tests that could be waived within the last few years, and this development is what created the main U.S. market opportunity for these products.

A CLIA waiver greatly expands the available potential U.S. market opportunity for a product from sites that require much greater certification and oversight (i.e. reference laboratories and hospitals) to additional venues where point of care testing is particularly beneficial (i.e. emergency rooms, doctors offices and public health clinics). There are approximately 189,000 testing sites across the United States that can use tests that are CLIA-waived. The United States Centers for Disease Control has issued recommendations that HIV testing become part of the routine medical care provided to all Americans between the ages of 13 and 64. Chembio's HIV barrel product was approved in 2006 by the FDA, initially as a moderately complex product. This approval was a prerequisite to submitting the CLIA Waiver Application.

According to Larry Siebert, CEO of Chembio, "Obtaining a CLIA-waiver for our HIV barrel test, combined with our HIV STAT PAK® cassette product which is already CLIA-waived, should significantly enhance the point-of-care rapid HIV product offering of our US marketing partner."
