Hematocrit is the percentage of red blood cells in the total blood volume. Red blood cells are vital to your health. Imagine them as the subway system of your blood. They transport oxygen and nutrients to various locations in your body. For you to stay healthy, your body needs to have the correct proportion of red blood cells.
Hematocrit is the proportion of your total blood volume that is composed of red blood cells. The ratio of red blood cells to the total blood volume is normally about 45 percent for men and 40 percent for women. CBC requires the ratio to be 38 percent red blood cells for you to donate.
