Chembio Ships First DPP® Tests

Milestone Reached With Patented Technology

MEDFORD, NY--(Marketwire - November 20, 2008) - Chembio Diagnostics, Inc. (OTCBB: CEMI) ("Chembio" or the "Company") has completed the first shipment of products based upon its patented Dual Path Platform or DPP® product technology. This shipment represents a significant milestone for the Company's strategy to develop OEM and branded products utilizing its Dual Path Platform technology and its development, regulatory and manufacturing capabilities.

This initial DPP® product is a rapid whole blood test for Canine Visceral Leishmaniasis which Chembio developed pursuant to one of the four technology transfer, supply and license agreements that Chembio executed this year with the Oswaldo Cruz Foundation ("FIOCRUZ") of Brazil. The initial shipment of approximately $120,000 is part of an initial order for this product of approximately $500,000, the balance of which the Company anticipates shipping prior to year-end.

Leishmaniasis is caused by a parasite that is transmitted by an insect vector. Two million new cases of leishmaniasis are estimated to occur annually, with an estimated 12 million people presently infected worldwide. Brazil in particular has experienced a sharp increase in the number of cases. Current eradication programs in Brazil are focused on vector canine populations. Dogs kept in the domestic environment are the principal animal reservoirs in Brazil, and children under the age of 15 years are the most severely affected age group. Currently used laboratory-based diagnostic technologies are impractical for determining whether these dogs are infected and therefore inevitably delay quarantine or other remedial actions upon such determination, hindering eradication efforts. Chembio's DPP® rapid test allows such determination and action to be taken at the point-of-use. The Chembio test is also more accurate than the existing laboratory technologies and rapid tests that are available.

As previously reported, Chembio has three other agreements in place with FIOCRUZ that were signed this year, including the most recently signed agreement for Chembio's DPP® HIV 1/2 test for use with oral fluid samples.

Chembio CEO Lawrence Siebert commented, "We are very pleased with the achievement of this milestone. Our patented technology enables immediate results, thereby lowering costs and improving outcomes. We are excited about the opportunities we have for this technology and I am most appreciative of the efforts that our entire staff has made in achieving this initial DPP® product shipment."
