Abstract

The invention discloses a novel direct bilirubin detection kit. The novel direct bilirubin detection kit consists of a reagent R1 and a reagent R2, wherein the reagent R1 consists of a Tris-HCl tartaric acid sodium hydroxide buffer solution, glycerine, dithiothreitol, silver nitrate, methyl isobutyl ketone, triton X-100, Na2-EDTA and oxammonium hydrochloride; the reagent R2 consists of sodium hydrogen phosphate, sodium biphosphate, sodium persulfate, Na2-EDTA and NaCl. All the components are scientifically combined, the accuracy in measuring a sample within 0-400 [mu]mol / L is relatively good, the precision is high, the repeatability is good, the anti-interference ability is strong, the reagents are relatively good in stability, and the novel direct bilirubin detection kit is suitable for a full-automatic biochemical analyzer and has a high clinical use value.

Description

technical field

[0001] The invention relates to the technical field of clinical in vitro detection reagents, in particular to a novel direct bilirubin detection kit. Background technique

[0002] Bilirubin contains two types: free bilirubin and direct bilirubin: direct bilirubin can also be called conjugated bilirubin, that is, free bilirubin in the blood is transported to the liver and is quickly taken up by liver cells. In the cytoplasm of liver cells, it is mainly combined with Y protein and Z protein (mainly Y protein). Then combine with glucuronic acid in the endoplasmic reticulum to generate water-soluble conjugated bilirubin; free bilirubin can also become unconjugated bilirubin, that is, not combined with glucuronic acid, unconjugated bilirubin is mainly heme in Under the catalysis of mononuclear phagocytic system cell microsomal heme oxygenase, the water-soluble biliverdin of linear tetrapyrrole is formed, and the biliverdin is further reduced under the catalysis o...
