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.
For anti-HIV immunoassay, an antigen is used to capture or react with antibodies raised against the infecting HIV of an infected person. For an antigen assay, the assay employs an antibody (usually monoclonal) to identify virus in an infected individual's plasma or serum. Immunoassays are available in different formats but they all employ the interaction and detection of an antibodyâantigen reaction. Since 1985, when commercial immunoassays for HIV detection first became available, there have been four successive generations of these tests used for screening and diagnosis.
