The proportion of the blood that consists of packed red blood cells. The hematocrit is expressed as a percentage by volume. The red cells are packed by centrifugation. For example, an hematocrit of 25% means that there are 25 milliliters of red blood cells in 100 milliliters of blood. The red cells make up a quarter of the blood. The normal ranges [..]

The amount of whole blood that is made up of red blood cells. It depends on the number and size of red blood cells. A hematocrit test is usually part of a complete blood count (CBC). It may be used to [..]

A laboratory measurement that determines the percentage of packed red blood cells in a given volume of blood. In women red blood cells are normally 37 to 47 percent of their blood, and in men red bloo [..]

Hematocrit is the percentage of the volume of a blood sample occupied by cells, as determined by a centrifuge or device which separates the cells and other particulate elements of the blood from the plasma. The remaining fraction of the blood sample is called plasmocrit (blood plasma volume).

A measure of the amount of red blood cells in your body.

the percentage of red blood cells found in blood. Prior to donating, hematocrit levels may be assessed to ensure that an acceptable red cell volume is present. Hemoglobin

Measure of the volume of red blood cells as a percentage of the total blood volume. Normal in males is 43-49%, in females 37-43%.
