Abstract

A whole blood hollow fiber membrane filter medium is provided with a ceramic material having pores of a pore size that ensures permeability to blood plasma or serum and its molecular components while blood cells are retained. The whole blood hollow fiber membrane filter medium is used for separating blood plasma from whole blood, wherein the blood plasma preferably shows no hemolysis.
