title: [Diagnostic importance of HDL cholesterol determination].
abstract: The present paper describes the sensitivity to quantification of changes of HDL-cholesterol in serum by two different precipitation and analytical techniques during the treatment of patients. After the precipitation of VLDL and LDL by phosphotungstic acid/magnesium chloride the chemical determination of HDL-cholesterol in serum with the Liebermann-Burchard reaction yields different results in comparison to enzymatic HDL-cholesterol determined in serum supernatant after the precipitation by polyethylene glycol 20.000. Correlation analyses of apolipoprotein A-I with enzymatic HDL-, HDL2-, HDL3-cholesterol or electrophoretic alpha-cholesterol demonstrate that the therapeutically induced changes (by training and diet) of lipid composition are more correctly reflected by the enzymatic determination of HDL-cholesterol after serum precipitation by polyethylene glycol.
