Abstract
An improvement in the degree of separation of constituent cell layers in a centrifuged sample of human blood is achieved by decreasing the natural water content of the red blood cells to increase their density or specific gravity. Thus the red cell layer packs more tightly and separates more completely from the next lighter cell layer adjacent thereto, i.e., the granulocyte layer.
