Hematocrit or Hct: Hematocrit refers to the ratio of the volume of red blood cells to the volume of the total blood. The hematocrit normal range varies between the genders and is about 37 percent to 48 percent in women, and 45 percent to 52 percent for men. The hematocrit values are usually determined by spinning down a blood sample in a test tube, which results in the accumulation of red blood cells at the bottom of the test tube.
