    摘要: A lytic reagent composition and methods for differential analysis of leukocytes are disclosed. In embodiments, the analysis may utilize optical measurements in flow cytometry based hematology analyzers. The reagent system includes an anionic surfactant in a hypotonic solution, an inorganic buffer to maintain the pH in a range from about 6 to about 10, and optionally a leukocyte stabilizer. The reagent system is used to lyse red blood cells and stabilize the leukocytes to enable multi-part differentiation of leukocytes in a near physiologic pH environment on a flow cytometry based hematology analyzer using axial light loss, light scatter intensity, high-numerical aperture side scatter, and time-of-flight measurements.
