The remainder of the blood is made up of white blood cells, platelets, serum, plasma and electrolytes. Hematocrit range varies with age and sex.

Ration of red blood cells to whole blood.
A test measuring the percent of red cells in a sample of whole blood, used to test for anemia.
The relative volume of red blood cells to the volume of whole blood; also, the instrument for measuring this ratio .
A way of measuring the red cell content of the blood. The normal level is about 40-45 in men and 37-42 in women. A low hematocrit is a sign of anemia.
Percent of the total blood volume that is made up of red blood cells.
percentage of packed red blood cells in a blood sample.
the percentage of red blood cells in a given amount of whole blood. The hematocrit reflects oxygen-carrying capacity; a drop in hematocrit may indicate bone marrow dysfunction. Red blood cells normally constitute about 38-54% of the whole blood in men and about 37-47% in women.
The percentage of red blood cells in the bloodstream.
The Hematocrit (HCT) and the Packed Cell Volume (PCV) indicate the percent of red blood cells in a unit of whole blood. They are equivalent measurements. The VetScan HMT calculates the HCT. It is equivalent to the manual centrifuge packing of red cells called the packed cell volume (PCV). When a blood sample is centrifuged (Spun Hematocrit), it separates into 3 layers: an upper layer of plasma; a middle layer of WBCs and thrombocytes (buffy coat); and a bottom layer of packed RBCs. Technically, the hematocrit is a measure of all the cellular elements of blood (WBCs, thrombocytes, RBCs). By common usage, however, it has become synonymous with packed cell volume (PCV). See also Packed Cell Volume.
a potential source of error in breath-alcohol analysis. Whole blood is made up of solid particles suspended in liquid. The percentage by volume of the solid particles is called the hematocrit of the blood. Breath machines report a falsely high blood alcohol reading for persons who have blood with a high hematocrit.
(HCT) hematocrit reflects the percentage of blood volume that is made up of red blood cells (erythrocytes).

A measure of the amount of red blood cells in your body.
The ratio of red blood cells to total blood volume, mormally about 38% - 46% in women and 42% - 54% in men. The measurement is often used to diagnose and determine the onset of anemia.
he- mat'o-krit] - A measurement of the percentage of red cells in the blood, which determines the ability of the blood to carry oxygen. A low hematocrit is known as "anemia". At WAWC, the hematocrit is measured with a drop of blood from a fingertip.

Hct) The percentage of red blood cells in whole blood. Normal hematocrit is from 37% to 47% for women and from 42% to 52% for men. The NKF-DOQI recommended target hematocrit range for dialysis patients is 33% to 36% and most patients need regular doses of EPO and iron to stay at this level. Without enough red blood cells to carry oxygen to the tissues, patients feel tired and listless.
