A test that combines radioactive chemicals and antibodies to detect minute quantities of substances in a patient's blood?
nirvana33 [79]

Radioimmunoassay (RIA) is a test that combines radioactive chemicals and antibodies to detect minute quantities of substances in a patient's blood.

In 1959, biophysicist Rosalyn Yalow and physician Solomon A. Berson developed a sensitive method for measuring very small amounts of a substance in the blood called radioimmunoassay (RIA).

Radioimmunoassay (RIA) is a technique that make use of radioisotopes, usually iodine-125, as a tag or label for the detection of antigen. This technique determines the concentration of an antigen based on the competitive binding between radiolabeled and unlabeled antigen for its specific high affinity antibody.

It is very sensitive that it can measure concentrations up to 0.001 μg/ml.
