Answer:
D) "The hematocrit measures the mass that your red blood cells account for in a quantity of your blood."
Explanation:
When going for a blood work, people diagnosed with anemia usually check their hematocrit.
The hematocrit is a test that reveals the mass of red blood cells in a person's blood count. It is used to determine whether or not a person has anemia. If the percentage of red blood cells is abnormally low, a person is diagnosed with anemia. The symptoms of anemia are paleness and weakness as well as fast heart rate and sensitivity to the cold.
