Abstract
A method for measuring concentrations of blood cell components is provided. The method comprises: obtaining a blood sample from a subject, the blood sample comprising red blood cells (RBCs), white blood cells (WBCs), and platelets (PLTs); mixing the blood sample with a non-lysing aqueous solution to form a sample mixture comprising a predetermined tonicity; passing the sample mixture through a flow cell; emitting light towards the flow cell; measuring an amount of light absorbed by the RBCs; measuring an amount of light scattered by WBCs, and PLTs; determining a concentration of each of the RBCs, WBCs, and PLTs present in the sample mixture from the measured amount of light absorbed by the RBCs and scattered by the WBCs and PLTs.
