Enzyme-Linked Immunosorbent Assay (ELISA) Audio


Synonym(s): Enzyme Immunoassay

A laboratory test to detect the presence of HIV antibodies in the blood, oral fluid, or urine. The immune system responds to HIV infection by producing HIV antibodies. A positive result on an enzyme-linked immunosorbent assay (ELISA) must be confirmed by a second, different antibody test (a positive Western blot) for a person to be definitively diagnosed with HIV infection.
