Abstract
Blood derived fluids are subjected to modification resulting in the production of anaphylatoxins. The anaphylatoxins may then be removed by passing the modified blood through silicic acid particles in an amount sufficient to substantially reduce the anaphylatoxins, while still retaining the other blood components and without affecting adversely the use of the blood for the patient.
