Blood Assurance has been providing a safe blood supply in Chattanooga and 47 other counties since 1973. Prior to that time, people in need of blood had to rely on friends and relatives. In addition to ensuring a plentiful supply of whole blood, Blood Assurance also distributes plasma and blood platelets, primarily to cancer patients. It was the parents of a cancer patient who established the Blood Assurance Foundation. The foundation gives scholarships to local high school seniors every year.
