Abstract

The invention discloses a high-density lipoprotein cholesterol 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 a composite stabilizer consisting of 4-FPBA, glucomannan, NaCl, propanediol, triton 100 and BSA into the reagent R2, the stability of the kit is effectively improved; and the linear range of the kit is also relatively wide, and the reagent accuracy is high, so that the kit can be 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 high-density lipoprotein cholesterol detection kit. Background technique [0002] High-density lipoprotein cholesterol (HDL-cholesterol; HDL-Ch) refers to the cholesterol carried by high-density lipoprotein molecules. It is an endogenous cholesterol ester that is reverse-transported, transported into the liver, and then cleared out of the blood. High-density lipoproteins contain 20% to 30% of the total cholesterol in humans. High-density lipoprotein cholesterol can be commonly understood as "good" cholesterol, anti-atherosclerotic cholesterol, because HDL-C can reduce the risk of coronary heart disease. [0003] HDL cholesterol is composed of apolipoproteins, phospholipids, cholesterol and a small amount of fatty acids. [0004] The reference range of high-density lipoprotein cholesterol in human serum or plasma is 0.77-2.25 mmol / L. Increase: The...
