Abstract
A method for carrying out separation of plasma from whole blood, in which whole blood is passed through a filtration membrane means of a material suitable for separating plasma from whole blood and having a pore size from 0.1 to 0.6 microns at positive pressure differential across the membrane in a range up to just below 50 mm Hg. This provides an increased flow as compared to the flow obtained with higher pressures.
