Chembio Diagnostics Obtains CE Mark for Its DPP® Syphilis Screen & Confirm Assay

MEDFORD, NY—October 11, 2011 -- Chembio Diagnostics, Inc. (CEMI.QB: CEMI.PK), which develops, manufactures, markets and licenses point-of-care diagnostic tests, announces that its DPP® Syphilis Screen & Confirm Assay has received a CE marking. The CE marking declares that a product has met all relevant European Union consumer safety, health or environmental requirements, and can therefore be sold within the European Economic Area.

The DPP® Syphilis Screen & Confirm Assay provides the most conclusive evidence available at the point-of-care (POC), of an active, previously untreated case of syphilis, thereby enabling diagnosis and treatment in a single visit to a clinic.

According to the World Health Organization, there will be 140,000 new cases of the disease in Europe this year alone, and 12 million new cases worldwide. Standard diagnosis of syphilis is currently analyzed using two different laboratory-based serologic tests, namely a non-treponemal screening test, usually either the Rapid Plasma Reagin (RPR) or Venereal Disease Research Laboratory (VDRL), followed by a more specific treponemal confirmatory assay. Chembio has developed the first dual non-treponemal & treponemal POC syphilis test that can be used in the European Union.

Utilizing Chembio’s patented Dual Path Platform technology, DPP® Syphilis Screen & Confirm permits the simultaneous yet separate detection of both markers at the point of care, eliminating the need and resulting cost of two separate laboratory tests. The Company has recently begun clinical trials at the first of three sites in the United States in support of an application to the FDA for a 510(k) clearance, which the Company anticipates submitting in 2012. The Company also anticipates that this test will be eligible for a CLIA waiver (Clinical Laboratory Improvement Act waiver) which, if granted, would allow use of the test in point-of-care settings such as public health testing clinics and physician (i.e., OB-GYN) offices for screening of pregnant women. Accordingly, the Company believes that the DPP® Syphilis Screen & Confirm represents a considerable advance in cost-effective, timely and simple diagnosis.

Lawrence Siebert, CEO of Chembio Diagnostics, commented, “Now that we have received CE certification, we intend to focus our efforts in the EU market in order to aggressively ramp up sales of our DPP® Syphilis Screen & Confirm Assay to meet that need, while we also move forward on our United States FDA regulatory pathway.
