Abstract

The invention discloses a blood alanine aminotransferase detecting reagent with high stability, and belongs to the technical field of clinical in-vitro detection. According to the blood alanine aminotransferase detecting reagent with high stability, disclosed by the invention, the blood serum alanine aminotransferase (ALT) is detected by using the single reagent method on the basis of an enzyme-coupled continuous detection method, so that the problem that the single reagent in the original formula is unstable is solved, and the reagent is simple and convenient to operate, and facilitates clinical application and popularization.

Description

technical field

[0001] The invention relates to a highly stable blood alanine aminotransferase detection reagent, which belongs to the technical field of clinical in vitro detection. Background technique

[0002] Alanine aminotransferase (ALT) is an enzyme involved in human protein metabolism (equivalent to a catalyst in industrial production), which plays a role in accelerating the transformation of protein amino acids in the body. It widely exists in various tissues, organs, Among the muscles and bones, the cytoplasm of liver cells is the most. The reference value of normal content of ALT in serum is: male 9-51U / L, female 8-41U / L (the test methods of each hospital are different, the reference value is not exactly the same ). When various tissues and organs in the human body are active or diseased, the ALT in them will be released into the blood, increasing the serum ALT content. For example, when the liver is inflamed, the transaminases will be released from the liver ce...
