Abdul Rehaman Asst prof M.ph.,PhD., PHARMACEUTICS NIRMALA COLLEGE OF PHARMACY. A radioimmunoassay (RIA) is an immunoassay that uses radiolabeled molecules in a stepwise formation of immune complexes.A RIA is a very sensitive in vitro assay technique used to measure concentrations of substances, usually measuring antigen concentrations (for example, hormone levels in blood) by use of antibodies Although the RIA technique is extremely sensitive and extremely specific. Radioimmune assay (RIA): As the name indicates, it is an immunological assay to analyze any antigen or antibody in the patient’s serum to diagnose the disease.

Radioimmunoassay- Principle, Uses and Limitations. The first immunoassay technique was the isotopic dilution radioimmunoassay, developed by Rosalyn Yalow and Solomon Berson for the detection of insulin in human blood.This work gained Yalow a share of the 1977 Nobel Prize for Physiology and Medicine, but Berson was not honored because of Nobel rules.
