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.
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.

enzyme-linked immunosorbent assay (ELISA), biochemical procedure in which a signal produced by an enzymatic reaction is used to detect and quantify the amount of a specific substance in a solution.
The Enzyme-Linked Immunosorbent Assay (ELISA) is a widely used laboratory technique for detecting and quantifying soluble substances such as peptides, proteins, antibodies, and hormones.
An ELISA test is a blood test that detects specific antibodies, antigens, or hormones in your body by using an enzyme-triggered color change. The name stands for enzyme-linked immunosorbent assay. It’s one of the most widely used diagnostic tools in medicine, capable of identifying everything from HIV and Lyme disease to pregnancy hormones and drug use. If your doctor has ordered one, it ...
