This invention provides a fail-safe combination of chemical and physical means to render a blood product, which contains labile blood proteins, free of viruses without causing protein denaturation. The blood product is treated with an effective amount of a selected chemical disinfectant, such as sodium thiocyanate, in conjunction with a physical process like ultrafiltration. This method is applicable to various blood products, including plasma and serum, that may contain viruses such as hepatitis or human immunodeficiency virus.
