Abstract
The present invention relates to a method for direct measurement of high-density lipoprotein cholesterol. (HDL-C) or low-density lipoprotein cholesterol (LDL-C) based on a modified chemical precipitation method, wherein the improvements were made by optimizing the concentrations and proportions of potassium polyvinyl sulfate (PVSK) and polyethylene glycol methyl ether (PEGME) in such a way that the enzymatic reactions are completed before precipitation formations. The method in combination with certain surfactants showed good correlations with other direct methods used for HDL-C or LDL-C determinations.
