Patent ID: 8785146

Claim:
A method for measuring the contents of high-density lipoprotein cholesterol in a sample, comprising the steps of: 1) contacting potassium polyvinyl sulfate and polyethylene glycol methyl ether with the sample, said potassium polyvinyl sulfate and polyethylene glycol methyl ether being in an optimized proportion and having optimized concentrations wherein said optimized proportion between potassium polyvinyl sulfate and polyethylene glycol methyl ether is 1:500-550, and said optimized concentrations thereof are 10-20 mg/L and 5 g-11 g/L, respectively for measurement of high-density lipoprotein cholesterol; 2) measuring the concentrations of high-density lipoprotein cholesterol in the sample enzymatically in combination with at least one surfactant before the formation of precipitation.
