Diagnostic reagents methodological classification

Clinical biochemical reagents

Clinical biochemical reagents are mainly measuring enzymes, carbohydrates, lipids, protein and non-protein nitrogen, inorganic elements, liver function, clinical chemistry control serum, and other major categories of products, the main is used in conjunction with manual, semi-automatic and general Automatic biochemical analyzer and other equipment testing, a single reagent, liquid double reagent, dry powder double reagent, chemical reagents, standards and other specifications, while the manufacturers are available for testing room, indoor quality control of quality control serum series.

Immunodiagnostic reagents

Immunodiagnostic reagents in the diagnostic kit most varieties, according to the diagnostic categories, can be divided into infectious diseases, endocrine, cancer, drug testing, blood type identification. Methodological judgments from the results can be divided into EIA, colloidal gold, chemiluminescence, isotopes and other different types of reagents, of which isotope radioimmunoassay reagents because of the larger environmental pollution, the current international market has been eliminated, there are A small amount of use.

Molecular diagnostic reagents

Molecular diagnostic reagents are clinically used nucleic acid amplification technology (PCR) products and is currently under intense research and development of gene chip products. PCR products have high sensitivity, specificity and short diagnostic window, which can be used for qualitative and quantitative detection. They have been widely used in the detection of hepatitis, STD, lung infectious diseases, prenatal and postnatal care, genetic disease genes and tumors. However, due to market turmoil And cross-contamination and other reasons, the Ministry of Health has strictly banned the clinical application of qualitative PCR reagents of fluorescent electrophoresis. At present, the SFDA has approved a few hybridized semi-quantitative and quantitative kits that have solved the cross-contamination. Gene chip is a combination of molecular biology, microelectronics, computers and other multidisciplinary integration of a variety of modern sophisticated technology, the experts as the diagnostic industry's ultimate product, but the high cost, the difficulty of development, the current product type is very Less, only for research and drug screening purposes.
