[Comparative study of the analysis of lipoproteins with different electrophoretic methods (author's transl)]

In 100 unselected sera the lipids were analysed with different methods. A commonly used method of the lipoprotein-electrophoresis, which evaluates the pherogram after staining with lipid-strains, was compared with the quantitative lipoproteinelectrophoresis according to Wieland and Seidel. The analyses were supplemented through the enzymatic estimation of total cholesterol and triglycerides. Only in 55 cases the results were identical. The improved diagnosis of lipoproteins is due to the complete and reproducible demonstration of HDL (high density lipoproteins) bands, which are found with the staining methods only in half of the cases. On the contrary the relative proportion of the VLDL (very low density lipoproteins) is increased three-fold with the staining methods.
