Enzyme Linked Immunosorbent Assay Law and Legal Definition

Enzyme linked immunosorbent assay or ELISA is a biochemical test used to find out if an individual is HIV positive. ELISA also screens for antibodies to determine the existence of other diseases. ELISA is also termed enzyme immunoassay or EIA.

Generally, an HIV test means ELISA. However, an HIV test can also include the Western Blot Assay.

The following is an example of a state law (California) defining the term:

According to Cal Ins Code § 799.01, "ELISA" test means an enzyme-linked immunosorbent assay serologic test which has been licensed by the federal Food and Drug Administration to detect antibodies to the human immunodeficiency virus.
