There are a variety of different types and formats of immunoassays. Homogenous immunoassays are often relatively simple as they require only one stop, mixing reagents and sample, before taking a measurement. Heterogeneous immunoassays may be run in multiple steps, with the addition and washing away of reagents, or the separation of the bound immune complex.

Ab-Ag complexes in immunoassays are detected using labeled material. The label reacts in the assay so that a change in signal can be measured. The measurement of labels may be carried out in a competitive or non-competitive format.

Analyte measurement is achieved using either a competitive or non-competitive format. In a competitive assay, unlabeled antigen in the patient sample is measured by its ability to compete with labeled antigen present in the immunoassay. If the unlabeled (test) analyte is occupying the antibody binding site...
