A method for detecting abnormality in the morphology of erythrocytes, which comprises:

Method for detecting abnormal morphology of erythrocytes

A hematological sample is treated with a hemolytic agent that maintains immature leukocytes in a viable state and damages other leukocytes. The damaged leukocytes are stained with a fluorochrome which can stain damaged cells. At least one kind of scattered light and at least one kind of fluorescence of the treated and stained blood cells are measured to classify and count leukocytes based on the intensities of the scattered light and the fluorescence. Highly precise measurement of immature leukocytes and simultaneous classification and counting of normal leukocytes are achieved.

Method for classifying and counting immature leukocytes

A reagent for measuring reticulocytes which has at least one dye which specifically stains reticulocytes and at least one dye which specifically stains leukocytes.
