WebWhen the hematocrit sample collection tube is filled with approximately 65 microliters of either capillary or venous blood, the dry reagents in the tube mix with the blood sample. A precision mechanical expander (float) in the tube expands the Buffy Coat (white blood cells and platelets) and allows the cells to be digitally imaged. WebMore commonly, automated analyzers determine hematocrit by directly measuring the red cell number divided by the red cell volume. These automated hematocrit values closely reflect manual measurements. Automated analyzers determine red blood cell counts via electrical impedance and/or light scatter.
