Abstract
A reagent for fractional measurement of small, dense LDLs without pretreatment of a specimen, which is adaptable to a rapid and convenient autoanalyzer, is provided. A method for quantitatively determining cholesterol in small, dense LDLs in a sample is further provided. The method includes first step of eliminating lipoproteins other than small, dense LDLs in a sample in the presence of cholesterol esterase and 0.05 g/L to 1.0 g/L of a surfactant that acts on the lipoproteins other than small, dense LDLs, and a second step of quantitatively determining cholesterol in small dense LDLs that remain after the first step.
