ELISA is an enzyme-linked immunosorbent assay (also known as EIA: Enzyme Immunoassay) technology used to detect and analyze antibodies, hormones, peptides, and proteins in the blood.
Antibodies are blood proteins produced in response to a specific antigen. In the case of some infectious disorders, it aids in determining the existence of antibodies in the body.
ELISA is different from other antibody assays in that it produces quantitative findings and separates non-specific and specific interactions that occur via repeated binding to solid surfaces, which is often a polystyrene multiwell plate.
