(Nasdaq:CEMI), a leader in point-of-care (POC) diagnostic tests and
technology, today announced the launch of the Company's U.S. sales and
marketing effort. Effective today, the Company has initiated sales of its
Chembio HIV 1/2 STAT-PAK^® Assay and its corresponding HIV Rapid Test Control
Pack, as well as the Company's proprietary DPP^® HIV 1/2 Assay and
corresponding DPP^® HIV 1/2 Control Pack in the United States. The Company has
also assumed all customer and technical support for its Chembio-branded
products in the U.S.

The Chembio HIV 1/2 STAT-PAK^® Assay is FDA-approved and CLIA-waived and has
been one of the leading diagnostics in the fight against HIV/AIDS since its
market introduction in 2006. The ease of use, small (5 µL) specimen
requirement, rapid and reliable results, long shelf life and room temperature
storage make it uniquely suited for clinical and outreach settings, allowing
immediate patient counseling and referral.

Chembio's DPP^® HIV 1/2 Assay detects HIV antibodies in oral fluid or blood
and uses our patented Dual Path Platform technology which offers excellent
sensitivity and specificity. Its unique SampleTainer^® specimen collection
bottle is a safe, closed system for collecting potentially infectious samples.

reliable and respected HIV diagnostics in the U.S., and we hope to leverage
our reputation for quality and innovation as we introduce our proprietary Dual
Path Platform (DPP^®) diagnostics to the market."
