摘要:
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.

Disclosed is a method for quantifying HDL2 cholesterol in a test sample without requiring laborious operations. The method for quantifying cholesterol comprises allowing phospholipase to act on HDL to quantify cholesterol. Also disclosed is a method comprising: a first step of transferring cholesterols other than high-density lipoproteins in a test sample to the outside of the reaction system; and a second step of quantifying high-density lipoprotein 2 cholesterol among the high-density lipoproteins remaining in the reaction system; wherein, by performing the second step by the above method, high-density lipoprotein 2 cholesterol in the test sample can be quantified.
