Chemiluminescent immunoassay utilizes a chemical or bioluminescent system as an indicator system for an antigen-antibody reaction, whereby an antigen or antibody is quantitatively detected. The chemical or biological luminescent substance can be directly used as antigen or antibody label, or can be used in free form in the luminescent reaction of the catalyst labeled and adjuvant labeled antibody or antigen. The free energy released by the chemiluminescent reaction excites the intermediate, so that the intermediate returns to the ground state from the excited state, and photons with equal energy level are released, and then the photons are measured by a chemoimmunoassay analyzer, so that the content of the measured object is accurately quantified.
