Chembio’s Dual Path Platform (DPP™) Patent Application Allowed

Platform for Next Generation Rapid Tests

New York, January 17, 2007- (OTCBB:CEMI) - Chembio Diagnostics, Inc. has received a Notice of Allowance from the United States Patent and Trademark Office for its Dual Path Immunoassay patent application publication #2006-0205059. The patent application describes Chembio’s innovative Dual Path Platform (DPP™) lateral flow rapid diagnostic test system. Chembio is developing its next generation infectious disease rapid tests using DPP™. Chembio also believes that its DPP^TM diagnostic test system can be licensed to other manufacturers that seek enhanced rapid test performance or where licenses to other lateral flow technologies are not as cost-effective or even available.

By employing a separate membrane strip for sample migration and one for the other test reagents, the DPP^TM diagnostic test system controls sample flow and immunological reaction more efficiently than conventional lateral flow tests. This feature improves sensitivity and specificity. The DPP^TM diagnostic test system is therefore well suited for use with a wide variety of sample types including whole blood, serum, fecal material, urine, sputum and oral fluid. More even distribution of sample material to multiple test lines in the DPP™ test zone as compared with conventional lateral flow also enables the development of combination and/or confirmatory assays with improved results, which can be developed so as to observe coded results visually or with instrumentation. Products can also be developed using DPP^TM diagnostic test systems in many areas beyond infectious diseases such as environmental testing, food testing, therapeutic monitoring and consumer diagnostics.

“Chembio has today achieved a significant milestone toward obtaining its first lateral flow patent in less than two years since our initial filing for this, a timeframe which I believe speaks to the innovation in this technology”, Chembio’s Chairman and President, Lawrence A. Siebert, said. Mr. Siebert continued, “I appreciate the commitment that our Vice President of Research & Development, Javan Esfandiari, has had in this project that is so central to our current and future product development activities.

In November 2006 Chembio announced a Cooperative Research & Development Agreement with the United States Centers for Disease Control for the development of a rapid “screen and confirm” combination test for syphilis that would employ the DPP^TM diagnostic test system. Other applications for the DPP^TM diagnostic test system, including an oral fluid HIV test, are under development and discussion with a growing number of parties. An animation showing the DPP^TM oral fluid HIV diagnostic test system can be viewed at the company’s web site through the following link: http://www.chembio.com/newtechnologies.html.

The Notice of Allowance means Chembio is entitled to a patent under the law subject only to payment of a specified issue fee within three months of the notice of allowance. Chembio has also filed for patent protection for the DPP^TM diagnostic test system in Brazil, Malaysia, and Thailand as well as through the Patent Cooperation Treaty which provides Chembio with the opportunity to file applications in more than 100 other foreign countries later this year.
