Abstract

This invention relates to a test kit for diagnosing hepatic and biliary diseases. The test kit has such advantages as high stability, high accuracy and high sensitivity. The test kit comprises two reagents. Reagent 1 comprises oxidized thio coenzyme, buffer solution, preservative, and anti-interference agent. Reagent 2 comprises 3alpha-HSD, reduced coenzyme, buffer solution, preservative, complexing agent, polymer accelerator, stabilizer, and one of formate dehydrogenase-formic acid-NAD, glutamate dehydrogenase-glutamic acid-oxidized nicotinamide coenzyme, glucose-6-phosphate dehydrogenase-glucose-oxidized nicotinamide coenzyme, glucose dehydrogenase-xylose-oxidized nicotinamide coenzyme, lactate dehydrogenase-alpha-ketoglutarate-oxidized nicotinamide coenzyme, and glycerol dehydrogenase-ethylene glycol-oxidized nicotinamide coenzyme.

Description

technical field [0001] The invention relates to a reagent for measuring serum components, in particular to a reagent for measuring serum bile acid, and belongs to the technical field of biological preparations. Background technique [0002] Medical research shows that the production and metabolism of bile acids are closely related to the liver, and the level of total bile acids in serum is an important indicator reflecting liver parenchyma damage, especially acute hepatitis, cirrhosis, and toxic hepatitis. Variety. However, its concentration in serum is very low (micromolar level), and it is difficult to detect. In the past, it was not practical due to the complexity of detection methods and the requirement of special equipment, and it was difficult to be used for automatic analysis, which limited its application in daily testing. [0003] In the past, the analysis of serum bile acids mainly used high-performance liquid chromatography (HPLC), HPLC-UV spectrometry, gas chrom...
