Abstract
A whole blood hollow fiber membrane filter medium is made of a polymeric material having pores of a pore size that ensures permeability to blood plasma or serum but retains blood cells. The whole blood hollow fiber membrane filter medium is used for filtering a whole blood sample so that blood plasma or serum passes through the whole blood hollow fiber membrane filter medium and blood cells are retained. The obtained blood plasma shows no hemolysis.
