what is immunoassay test f
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.uch assays are called homogenous immunoassays or less frequently non-separation immunoassays. The use of a calibrator is often employed in immunoassays. Calibrators are solutions that are known to contain the analyte in question, and the concentration of that analyte is generally known.
