Radioimmunoassay is based on the high sensitivity, accuracy andAntigen antibody reactionA quantitative method for the determination of trace substances in the liquid phase was established by combining the specificity of.[1]
Radioimmunoassay (RIA) usesRadionuclideIt is a radionuclide in vitro detection method that combines the measurement method of TNF and the basic principle of immune response.This method has the advantages of high sensitivity, strong specificity, good accuracy and less sample consumption, so it has developed rapidly.This testing technique is not only widely used to determine proteins, enzymes and polypeptide hormones with antigenicity, but also more and more widely used to determine many drugs without antigenicity.

Although RIA has many advantages, it also has many disadvantages.For example: ① The half-life period of reagents is expensive and requires special equipment such as scintillation counter; ②Radionuclide has certain potential harm to human body; ③Difficulty in treatment of test waste; ④Radionuclide labeling sometimes changes the physiological activity of some biological substances.[2]
