Abstract
The present invention relates to a method of maturity classifying reticulocytes from a whole blood sample, comprising: staining the sample with a supravital agglutinating dyeing reagent or a fluorescent agglutinating dye; illuminating the stained sample with a light beam to detect reticulocytes; determining for each reticulocyte the parameters of (i) a fraction (Λ) of the reticulum area (Ar) to the whole cell area (Ac); and (ii) a fraction (Γ) of the perimeter of the reticulum (Ur) to the reticulum area (Ar); and maturity classifying a reticulocyte into 1 of 4 major maturity classes according to the values determined for Λ and Γ.
