Enzyme-linked immunosorbent assay (ELISA) also known as an enzyme immunoassay (EIA), is a biochemical technique used mainly in immunology to detect the presence of an antibody or an antigen in a sample. It is used as a diagnostic tool in medicine and pathology, as well as a quality-control test across industries. EIA tests serve as a useful tool for determining serum antibody concentrations such as the HIV test since it can be performed to evaluate either the presence of antigen or the antibody in a sample.
