The<unk>  () <unk> t or<unk> CT), also known by several other names, is the volume percentage (vol%) of red blood cells (RBCs) in blood, measured as part of a blood test. The measurement depends on the number and size of red blood cells. It is normally 40.7–50.3% for males and 36.1–44.3% for females. It is a part of a person's complete blood count results, along with<unk> emoglobin concentration, white blood cell count and platelet count. Because the purpose of red blood cells is to transfer oxygen from the lungs to body tissues, a blood sample's<unk> —the red blood cell volume percentage—can become a point of reference of its capability of delivering oxygen.<unk>  levels that are too<unk> igh or too low can indicate a blood disorder, dehydration, or other medical conditions. An abnormally low<unk>  may suggest anemia, a decrease in the total amount of red blood cells, while an abnormally<unk> igh<unk>  is called polycythemia. Both are potentially life-threatening disorders.
