Causes of Elevated Hematocrit and Hemoglobin. When the hematocrit value is higher than the normal range, it is usually indicative of an elevated red blood cell count. Hematocrit values could be affected by the size, as well as the numbers of the red blood cells. High hemoglobin and hematocrit could be a sign of polycythemia vera.
