Abstract

There is provided a method of analyzing a biological sample component that allows easy and accurate quantification and counting of any of a plasma component and a blood cell component in a trace and unknown amount of a whole blood sample collected from a finger, for example. The method of the present invention is a method of analyzing a biological sample component in a trace amount of blood, comprising analyzing a diluent buffer into which the blood has been mixed and an internal standard substance and/or an external standard substance contained in the diluent buffer, calculating a dilution ratio, and analyzing a biological component in a plasma or serum component in the blood.
