title: Turbidimetric determination of lipoprotein-X in serum.
abstract: Turbidimetric determination of the cholestasis characterizing lipoprotein-X is based on the separation from the serum investigated of interfering lipoproteins by precipitation with the appropriate concentration of heparin and zinc acetate followed by centrifugation. In the supernatant the abnormal lipoprotein-X, which is not precipitated under these conditions, was determined by measuring the turbidity after addition of calcium chloride and heparin.
