Avitar

Avitar, Inc. was a medical technology company that developed and commercialized proprietary oral fluid diagnostic devices and disease-management products. The company's flagship product, ORALscreen, was the first rapid onsite oral fluid test for drugs of abuse, offering a non-invasive alternative to traditional urinalysis. Avitar also developed the HYDRAscreen pregnancy test and other clinical diagnostics based on its proprietary absorbent foam collection technology. Headquartered in Canton, Massachusetts, the company served the workplace testing, criminal justice, and clinical markets. The company's technology utilized a specialized polyurethane foam for the collection of saliva, which was then analyzed via lateral flow immunoassay. Despite its innovative diagnostic platform, the company faced significant financial challenges and was eventually delisted from public exchanges, with its SEC registration revoked in 2011.
