Jan 2, 2023 · The term "hematocrit (HCT)" originated from English “hemato-“ and Greek “krites.”. HCT measures the volume of packed red blood cells (RBC) relative to whole blood. Hence, it is also known and reported as a packed cell volume (PCV).
Hematocrit levels that are too high or too low can indicate a blood disorder, dehydration, or other medical conditions. [4] An abnormally low hematocrit may suggest anemia, a decrease in the total amount of red blood cells, while an abnormally high hematocrit is called polycythemia. [5]

The hematocrit measures the volume of red blood cells compared to the total blood volume (red blood cells and plasma). The normal hematocrit for men is 40 to 54%; for women it is 36 to 48%. This value can be determined directly by microhematocrit centrifugation or calculated indirectly.
Jun 2, 2022 · Hematocrit measures the percentage of red blood cells in the total blood volume. A hematocrit test can be performed using a capillary tube and a centrifuge machine (i.e., a machine using centrifugal force to separate the substances of the blood due to their different densities).
A hematocrit level that's lower than normal may be a sign that: Your body doesn't have enough red blood cells (anemia). There are many types of anemia that can be caused by different medical conditions.
Hematocrit may indicate that a patient has anemia, erythrocytosis, or changes in plasma volume. Hematocrit may be used as a cutoff to determine transfusion requirements. Following...
