American Bio Medica Offers Test for Buprenorphine.

KINDERHOOK, N.Y. -- American Bio Medica Corporation (NASDAQ: ABMC) today announced they have begun offering a point of collection drug screen that detects the presence or absence of buprenorphine in a urine specimen. Buprenorphine is a drug being used in a new office-based treatment for addiction to prescription pain relievers and other opiate drugs, including heroin. While the drug is intended to aid in addiction treatment, buprenorphine is potent (20 to 50 times the analgesic potency of morphine), has a long duration of action, and does not need to be injected, therefore the potential for abuse is high.

Stan Cipkowski, ABMC Chief Executive Officer stated, "Many of our customers in Europe indicated a need for a screen for buprenorphine so we developed a test to meet those needs. It is available in a single test or can be inserted into one of our multi panel devices. This is just another example of ABMC's ability to customize our products to meet the ever changing needs of the drugs of abuse testing market."

The product is currently available to non-clinical markets. ABMC plans to submit their screen for buprenorphine to the FDA for clinical marketing clearance.
