CLIA (Chemiluminescent immunoassay) A method in which after an antigen is reacted with a solid-phase antibody, an enzyme-labeled antibody is reacted with the antigen in a secondary reaction, in which the luminescence intensity of a chemiluminescent substrate is measured.
ECLIA (Electro chemiluminescence immunoassay) Electrochemiluminescence immunoassay A method to measure the luminescence intensity of ruthenium pyridine complexes by electrochemical reaction, in which antibody-conjugated beads are used to react with antigens, followed by a secondary reaction of antibodies labeled with ruthenium pyridine complexes with the antigens.

RIA (Radio immunoassay) Radioimmunoassay A method to perform the competitive antigen-antibody reaction between the antigen labeled with radioisotope (RI) against the antibody and the antigen in the specimen, and to separate the labeled antigen bound to the antibody (bound type: Bound) from the labeled antigen not bound to the antibody (free type: Free) and to measure the ratio of them as the antigen concentration from the radioactivity. As separation methods for bound and free types (B/F separation), there are the solid-phase method in which the antibody is solid-phased, the two-antibody method in which a second antibody is bound to the antigen-antibody complex and precipitated, the ammonium sulfate precipitation method in which the antigen-antibody complex is precipitated with ammonium sulfate (ammonium sulfate), and the PEG method in which the antigen-antibody complex is precipitated with a precipitation reagent.
