Patent ID: 8268626

Claim:
A method of analysis of lipoprotein particles comprising the steps of: separating a plurality of classes of lipoproteins contained in an obtained subject sample by liquid chromatography and detecting signals of VLDL, LDL and HDL in the separated lipoprotein particles, wherein each of the lipoprotein particles is constituted of subclasses estimated from chromatogram component peaks consisting of anchor peaks and extra essential peaks, wherein the chromatogram component peaks are curves obtained by separating a chromatogram curve signal associated with said subject sample into multiple curves, and calculating an approximated curve corresponding to summation of the chromatogram component peaks using said detected signals, wherein elution position(s) of one or more anchor peak(s) of said anchor peaks are determined by elution positions observed in a metabolic disorder patient whose lipoprotein metabolism suggests that the size ranges of VLDL, LDL, and HDL are narrow.
