An immunoassay is a biochemical test that measures the presence or concentration of a macromolecule in a solution through the use of an antibody or immunoglobulin.The macromolecule detected by the immunoassay is often referred to as an  analyte  and is in many cases a protein.mmunoassays rely on the ability of an antibody to recognize and bind a specific macromolecule in what might be a complex mixture of macromolecules. In immunology the particular macromolecule bound by an antibody is referred to as an antigen and the area on an antigen to which the antibody binds is called an epitope.
Immunoassay is the oldest, most well-known, and widely used of these three field analytical technologies. Although, in general, clinical chemistry has used immunoassay for many years, the approach began to be used in the environmental field in the early 1990s, when test kits became commercially available.he amount of the enzyme conjugate that remains in the test tube is measured through the use of a colorimetric reaction. An enzyme substrate and a chromogen are added to the test tube to cause the formation of the color. That action also is a timed step, after which a solution is added to stop the formation of color.
