What is OraSure HIV test?
OraSure is the name of a collection device for standard antibody testing which is inserted into the mouth. OraSure absorbs oral mucosal transudate*, rather than saliva, for testing. OraSure collects antibodies, not HIV itself. There is not enough HIV in saliva to be infectious. *Transudate is a fluid that passes through a membrane which filters out much of the protein and cellular elements to yield a watery solution. A transudate is due to increased pressure in the veins and capillaries forcing fluid through the vessel walls. It is a filtrate of blood. The transudated fluid accumulates in tissues outside the blood vessels.
