Abstract
The present invention is a method for blood analysis which provides a rapid treatment of a blood sample so that it can be analysed for counting and classification of leukocytes. Leukocytes are permeablized by treatment with a surfactant solution and labeled, preferably with a fluorescent dye. The method provides labeled leukocytes that can be counted and classified by optical means, including flow cytometry by analysis of a fluorescence signal.
