    • A method that enables quantification of cholesterol in high-density lipoprotein 3 (HDL3) in a test sample without requiring a laborious operation is disclosed. The method for quantifying cholesterol in HDL3 having: Step 1 wherein a surfactant that reacts with lipoproteins other than high-density lipoprotein 3 is reacted with a test sample to transfer cholesterol to the outside of the reaction system; and Step 2 in which cholesterol remaining in the reaction system is quantified. The method enables specific quantification of HDL3 cholesterol in a test sample using an automatic analyzer without requirement of a laborious operation such as ultracentrifugation or pretreatment. Further, quantification of the HDL2 cholesterol level can also be carried out by subtracting the HDL3 cholesterol level from the total HDL cholesterol level obtained by a conventional method for quantifying the total HDL cholesterol in a test sample.
    • 公开了一种能够在测试样品中定量高密度脂蛋白3(HDL3)中的胆固醇而不需要费力操作的方法。 用于定量HDL3中胆固醇的方法具有以下步骤:其中将与高密度脂蛋白3以外的脂蛋白反应的表面活性剂与测试样品反应以将胆固醇转移到反应体系外; 和步骤2,其中量化反应体系中剩余的胆固醇。 该方法可以使用自动分析仪在测试样品中进行HDL3胆固醇的特异性定量,而无需费力操作,如超速离心或预处理。 此外,HDL2胆固醇水平的定量也可以通过从测定样品中用于定量总HDL胆固醇的常规方法获得的总HDL胆固醇水平中减去HDL3胆固醇水平来进行。

    • This invention provides a method for separately or simultaneously quantifying cholesterol in a total amount of HDL-C, cholesterol in an HDL subfraction of apoE-containing HDL-C, and cholesterol in an HDL subfraction of apoE-deficient HDL-C. The method comprises enzymatically and separately quantifying cholesterol in apoE-containing HDL and cholesterol in apoE-deficient HDL by adding a surfactant selected from the group consisting of a surfactant with an apoE-containing HDL response rate/apoE-deficient HDL response rate ratio of 0.7 to less than 1.3, a surfactant with an apoE-containing HDL response rate/apoE-deficient HDL response rate ratio of less than 0.7, and a surfactant with an apoE-containing HDL response rate/apoE-deficient HDL response rate ratio of 1.3 or more to a test sample, allowing cholesterol esterase and cholesterol oxidase to react therewith, and quantifying the hydrogen peroxide generated.
