Abstract
THE concentration of red cells is not the same in all parts of the circulatory system1, the cell plasma ratio being lower in the capillaries and small vessels than in the larger arteries and veins. The over-all cell percentage (body hæmatocrit) is determined from the direct measurement of both red cell volume and plasma volume, and from this the body/venous hæmatocrit ratio (BH/VH ratio) is calculated. In normal adults resident at sea-level the BH/VH ratio averages 0.91 (ref. 2).
