Abstract
A method for classifying leukocytes with a flow cytometer by use of optical measurements on fluorochrome-stained blood cells. The method comprises the steps of lysing erythrocytes in a blood sample, selectively staining eosinophils and basophils, permitting stained sample to flow through a flow cytometer, and identifying and counting the type of each leukocyte.
