Patent ID: 11841358

Abstract:
Disclosed are a method for determining a platelet concentration of a blood sample, a hematology system (100) and a storage medium. The method for determining a platelet concentration in a blood sample includes: forming a first suspension by mixing a first aliquot of the blood sample with a diluent; forming a second suspension by mixing a second aliquot of the blood sample with a lytic agent and a fluorescent dye to lyse red blood cells and stain white blood cells; measuring DC impedance signals of the first suspension passing through an aperture; measuring light scatter signals and fluorescent signals of the second suspension passing through an optical flow cell (20); analyzing DC impedance signals of the first suspension to obtain a first platelet distribution; analyzing light scatter signals and fluorescent signals of the second suspension to differentiate platelets from white blood cells and to obtain a second platelet distribution; and determining platelet data, such as the platelet concentration of the blood sample using the first and second platelet distributions.
