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).

HCT and HGB are extremely common blood tests, which are usually measured together. HCT -- short for hematocrit -- is the volume of red blood cells (RBCs) within a specific volume of blood. HGB -- or hemoglobin -- is the amount of HGB in a specific volume of blood. As HGB is the oxygen-carrying protein within RBCs, the HCT and HGB are closely linked. When one falls, the other generally falls as well. Both HCT and HGB provide approximations of the number of RBCs contained in the blood, and low values indicate the presence of anemia. Low HCT and HGB may be caused by a reduced total number of RBCs or by excessive fluid within the blood, which dilutes the RBCs. The number of RBCs may be reduced by blood loss, impaired RBC production or excessive RBC destruction.
