How safe is the blood that is transfused to patients?
Nothing biologic is ever going to be 100% safe, but blood is very safe today and becoming safer as additional testing becomes available. Currently, we test every unit of blood for AIDS, Syphilis, two types of Hepatitis, and the West Nile Virus. In addition, we rely on donors to supply us with accurate information that allows us to exclude from the donor pool anyone whose activities are considered high risk.
