A low hematocrit means the percentage of red blood cells is below the lower limits of normal (see above) for that person's age, sex, or specific condition (for example, pregnancy or high-altitude living).Another term for low hematocrit is anemia. Causes of low hematocrit, or anemia, include:1  Bleeding (ulcers, trauma, colon cancer, internal bleeding). 2  Destruction of red blood cells (sickle cell anemia, enlarged spleen). 3  Decreased production of red blood cells (bone marrow supression, cancer, drugs). 4  Nutritional problems (low iron, B 12, folate and malnutrition).

Hematocrit (Hct) Levels. This is the ratio of the volume of red cells to the volume of whole blood. Normal range for hematocrit is different between the sexes and is approximately 45% to 52% for men and 37% to 48% for women.This is usually measured by spinning down a sample of blood in a test tube, which causes the red blood cells to pack at the bottom of the tube.he hematocrit is the proportion, by volume, of the blood that consists of red blood cells. The hematocrit (hct) is expressed as a percentage. For example, a hematocrit of 25% means that there are 25 milliliters of red blood cells in 100 milliliters of blood.
