Basis of the Test
The enzyme-linked immunosorbent assay (ELISA), also known as an enzyme immunoassay (EIA), detects HIV antibodies and antigens in the blood. Antibodies are proteins produced by the immune system, which helps your body fight disease. The immune system produces the antibodies in response to the presence of foreign substances, such as viruses. By contrast, antigens are any foreign substance in the body that causes the immune system to respond.
