1. What is biochemical analysis?

Biochemical analysis refers to the detection methods used to determine enzymes, carbohydrates, lipids, protein and non-protein nitrogen, inorganic elements, liver function and other indicators in the body through various biochemical reactions. It is mainly used in routine testing in hospitals.

The development of biochemical diagnosis has been relatively mature, and it is a routine diagnosis and testing item in hospitals, focusing on the monitoring of diseases that have occurred.

At present, the variety of biochemical diagnostic reagents is complete. Chinese brands have already occupied about two-thirds of the domestic biochemical diagnostic reagent market by virtue of their advantages in product cost performance and high-quality market services.

2. What is immunoassay?

Immunoassay is a highly selective diagnostic method established by the specific and specific reaction between the test substance and its corresponding substance. It is often detected by the immune response of antigen and antibody, and the detection is enhanced by amplifying the reaction signal by various carriers. Sensitivity (labels are isotopes, enzymes, chemiluminescent substances).

Immunoassays include radioimmunoassays, enzyme-linked immunoassays, chemiluminescence, etc. It mainly tests small molecular proteins, hormones, fatty acids, drugs and other substances in the body. It is often used for infectious diseases, endocrine diseases, tumors, pregnancy tests, blood group antigens and other proteins. Target detection.

At present, high-end chemiluminescence has gradually replaced enzyme-linked immunoassay as the mainstream immunodiagnostic method, focusing on the monitoring of infected diseases.

(1) Enzyme-linked immunoassay

Enzyme-linked immunoassay markers are enzymes, which are often used to detect an antigen or antibody. Reagents have the characteristics of low cost and large-scale operation, and are currently the mainstream of immunodiagnostic reagents in China.

(2) Chemiluminescence

Chemiluminescence reagents have high sensitivity, strong specificity, and good reproducibility, which can be used for highly automated semi-quantitative and quantitative analysis, and the detection time is fast and the reproducibility is good, which is an important development direction of immunoreagents one.

A picture shows you the difference between the biochemical analysis and immunoassay.
