Abstract

The invention discloses a glutamate dehydrogenase detection kit, and belongs to the technical field of clinical in-vitro detection reagents. The kit comprises a reagent R1, a reagent R2 and a calibration product. By adding of AEO (alkyl polyoxyethylene ether)-9 into the reagent R2, the problem of low repetitiveness of the reagent is solved; the glutamate dehydrogenase detection kit is relatively wide in linearity range, high in reagent accuracy, and favorable for being further popularized and used in the market.

Description

technical field [0001] The invention relates to the technical field of clinical in vitro detection reagents, in particular to a glutamate dehydrogenase detection kit. Background technique [0002] Glutamate dehydrogenase (GLDH or GDH) is an enzyme that mainly exists in the mitochondrial matrix of cells, with the highest content in the liver, followed by kidneys, pancreas, brain, small intestinal mucosa, and heart. Its determination method is mainly continuous monitoring method. [0003] The activity of GLDH in the blood of normal people is very low, and the reference value range is: 0-12.2U / L. It enters the blood when liver cell necrosis occurs. Therefore, the activity of GLDH increases significantly in liver diseases, especially when liver cell mitochondria are damaged, so it is commonly used It is a sensitive indicator of liver parenchyma damage. The activity of GLDH in the serum increases significantly in alcohol poisoning with hepatic necrosis, chronic hepatitis, hepat...
