Analysis of whole blood in medical diagnostics often requires the removal of colored constituents, the red blood cells, from blood samples. A filter medium has been developed for removal of red cells from blood, leaving clear serum available for further analysis. The filter is a composite wet-laid nonwoven containing cellulose, glass, synthetic staple,and synthetic binder fibers. In addition to the serum separation, the nonwoven filter exhibits high tensile strength for efficient automated converting and handling.
