Haematocrit (PCV)(%)

Haematocrit (PCV) is a measure of the percent of red cells to blood volume. This is done by centrifuging blood in a microhaematocrit tube and the proportion of packed red cells (in mm) expressed as percentage of the total volume. Hematocrit is measured by the direct reading of a blood-filled tube that has previously been centrifuged, or it is calculated from the hemoglobin by an electronic cell counting device (Schalm, 1975; http://www.aum.iawf.unibe.ch/HemoSurf/Data_E/Info/PaRB.htm).
