Traditional ELISA typically involves chromogenic reporters and substrates that produce some observable color change to indicate the presence of antigen or analyte. Newer ELISA-like techniques use fluorogenic, electrochemiluminescent, and quantitative PCR reporters to create quantifiable signals.
ELISA is a laboratory technique that detects certain antibodies, antigens and other substances in your blood, pee or other bodily fluid. Laboratory scientists use this technique for several medical tests — from diagnosing infections to confirming pregnancy.

ELISA uses a specific antibody with a covalently coupled enzyme. The amount of antibody that binds the antigen is proportional to the amount of antigen present, which is determined by spectrophotometrically measuring the conversion of a clear substance to a colored product by the coupled enzyme.
Each ELISA measures a specific antigen, and kits for a variety of antigens are widely available. The ELISA pictured in Figure 1 is what is known as a sandwich ELISA, here two sets of antibodies are used to detect secreted products, e.g. cytokines. The method is stepwise in the order shown.
