Description

Technical Field

[0001] The invention belongs to the technical field of medical equipment, and in particular relates to an automatic sample adding machine and an automatic sample adding method. Background Art

[0002] Chemiluminescent immunoassay is a technique that combines highly sensitive chemiluminescent assay technology with highly specific immune reactions, and is used for the detection and analysis of various antigens, haptens, antibodies, hormones, enzymes, fatty acids, vitamins and drugs. It is the latest immunoassay technology developed after radioimmunoassay, enzyme immunoassay, fluorescence immunoassay and time-resolved fluorescence immunoassay. The chemiluminescent diagnostic system uses the catalysis of chemiluminescent substances and the oxidation of oxidants to form an excited intermediate. When this excited intermediate returns to a stable ground state, it emits photons (hM) at the same time, and the light quantum yield is measured using a luminescent signal measuring instrument. The immune reaction system is to directly label the luminescent substance (excited intermediate generated under the excitation of the reactant) on the antigen (chemiluminescent immunoassay) or antibody (immunochemiluminescent assay), or the enzyme acts on the luminescent substrate. Currently, chemiluminescence diagnosis is widely used, such as the detection of infectious diseases, HBsAg, HBsAb, HBeAb, etc.; or thyroid function testing, TT3, TT4, T3, etc.; or tumor marker detection, AFP, CEA, PSA, NSE, CA50, etc.
