A method is provided for discriminating white blood cells from red blood cells and platelets in an unlysed, whole blood sample.

A red light absorbing fluorescent dye is utilized along with a measurement system comprised of a red light source and suitable detectors for red fluorescence, forward light scatter and right angle scatter.
