CANTON, Mass.--(BUSINESS WIRE)--Avitar Inc. (“AVTI”) (OTCBB:AVTI), manufacturers of nationally branded oral fluid testing diagnostic devices and customized polyurethane applications used in wound dressings, announced today that, because of a recent GAO study of the Department of Transportation urine-based testing procedures and their high rate of failures, the patented Avitar ORALscreen® technology will quickly gain favor. Drug abuse remains a major problem in the transportation sector, as well as construction, manufacturing, hospitality, and retail, due to the limitations associated with urine-based drug testing.
