Abstract
A blood treatment material adsorbs and removes blood components such as activated leukocytes and inflammatory cytokines with a high efficiency. The blood treatment material includes a water-insoluble material in the form of fibers or particles, wherein the difference between the maximum value (RaA) and the minimum value (RaB) of the arithmetic average roughness (Ra) of the surface of the water-insoluble material, as calculated using a laser microscope, is from 0.30 to 1.50 μm.
