What is the hematocrit?
The hematocrit is specifically a measure of how much of the blood is made of red cells. The hematocrit is a very convenient way to determine whether the red blood cell count is too high, too low, or normal. The hematocrit is a measure of the proportion of blood that is composed of the red blood cells.
How is hematocrit determined?
The red blood cells in the sample of blood are packed down by spinning the tube in a centrifuge under prescribed conditions. The proportion of the tube that consists of red blood cells is then measured. Let's say that it is 45%. The hematocrit is 45%.
