The venous blood from which the plasma/serum is manufactured has been tested for Hepatitis B surface antigen and Hepatitis C virus and found to be non-reactive by a currently approved FDA test. The blood has also been tested for Human immunodeficiency virus antibodies and found to be non-reactive. In accordance with current Good Manufacturing and Laboratory Practices (cGMP and GLP's), any protein of human blood origin should be handled as if capable of transmitting infections. Human Sera are supplied as "converted" which are derived from plasma, or "off the clot" which are from naturally clotted whole blood collected in containers without anticoagulant. These products are intended for in-vitro use only.
