Total blood volume (in ml) per body weight (in kg) is important in medical research. For healthy adults, the red blood cell volume mean is about u = 28 ml/kg.| Red blood cell volume that is too low or too high can indicate a medical problem. Suppose that Roger has had seven blood tests, and the red blood cell volumes were as follows. 32 25 42 34 32 39 31 Total blood volume gon mb per body weight for bot is important in medical research, For healthy adults, the red blood cell volume mean is about a = 28 mikg.
