WebRadioimmunoassay and immunoradiometric assay (IRMA) RIA and IRMA methods are capable of measuring the primary reaction between hapten (hapten is an incomplete antigen that cannot elicit an immune response by itself but can react with antibody of block a specific antigen–antibody complex) or antigen and a single antibody. WebRadioimmunoassays (RIAs) use antibodies to detect and quantitate the amount of antigen (analyte) in a sample. These assays are typically very sensitive and specific. It is possible to detect as low as a few picograms of analyte in the experimental tube when using antibodies of high affinity (Kd = 10 -8 - 10 -11 M).
