[Classification and supervision of hyperlipemias (author's transl)].

Different methods for determination and classification systems of serum lipoproteins were used and compared in 300 patients with hyperlipidemia. The procedures and methods were examined to find out which would provide a useful classification for diagnosis and therapy. Lipid electrophoresis on agarose gel gave no reliably reproducible typing. With acetate and polyacetate foils, Type llb was not recognizable in the majority of cases. Neither the determination of beta-cholesterol after polyanion precipitation nor quantitative lipid electrophoresis calculating the values as lipoprotein lipid gave type determinations which completely agreed with the ultracentrifuge, but the best coincidence with the ultracentrifuge was obtained with these two methods. The second method is chiefly suitable for supervision.
