A test that indicates whether you have too few or too many red blood cells is called hematocrit test (Hct). A hematocrit is the proportion of your total blood volume that is composed of red blood cells.
The one that transports the oxygen are the red blood cells. A sample of your blood is the one that they need and the technician will put the sample in a centrifuge device that spins the blood.
This will separate your blood into three parts: plasma, red blood cells, and other blood cells. This test is also called packed cell volume (PCV).
