Detailed explanation-1: -Hematocrit is the fraction of whole blood composed of red blood cells. Hematocrit rises with an increase in the number of red blood cells or a decrease in the plasma volume. Conversely, hematocrit decreases when plasma volume increases or in states of decreased erythropoiesis or increased red cell destruction or loss.
Detailed explanation-2: -Hematocrit is the percentage of red cells in your blood. Normal levels of hematocrit for men range from 41% to 50%. Normal level for women is 36% to 48%.
Detailed explanation-3: -The hematocrit measures the volume of red blood cells compared to the total blood volume (red blood cells and plasma). The normal hematocrit for men is 40 to 54%; for women it is 36 to 48%. This value can be determined directly by microhematocrit centrifugation or calculated indirectly.
Detailed explanation-4: -Typically 4–6 million RBCs per cubic millimeter occupy 41–52% of blood volume (hematocrit).
