C
Hematocrit is the percentage of blood volume that packed red blood cells represent. Responses A, C, and D are incorrect. Hematocrit does not measure hemoglobin level or the oxygen-carrying capacity of the red blood cells. Hematocrit is measured as a percentage; it is not a count of the total number of red blood cells. Hematocrit is not a comparison of red blood cells and white blood cells.
