Detailed explanation-1: -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%.
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: -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-4: -Other RBC measurements The hematocrit reflects the amount of space in the blood that is occupied by RBCs. Hematocrit measurements are affected by the number of RBCs and by the size of the RBCs. The mean corpuscle (cell) volume (MCV) is a measurement of the average size of the RBCs.
