METHOD FOR MEASURING AN AMOUNT OF LDL-CHOLESTEROL

摘要

Disclosed are a method for measuring the amount of cholesterol in low density lipoproteins (LDL-cholesterol) in a sample specifically and with accuracy and a reagent used in this method. The method and reagent employ an amphoteric surfactant and an aliphatic amine having a carboxyl or sulfonic acid group which inhibit cholesterol in lipoproteins other than low density lipoproteins from involving reactions for measuring the amount in cholesterol. The method allows the direct measurement of LDL-cholesterol by widely used automatic analyzers in a manner not possible using known methods.
