American Red Cross Biomedical Services plays a critical role in our nation’s health care system. It is the largest single supplier of blood and blood products in the United States, collecting and processing approximately 40 percent of the blood supply and distributing it to about 2,600 hospitals and transfusion centers nationwide. The Red Cross also plays a leading role in protecting the safety of donors and patients and increasing the availability of blood. It has been among the first to help develop and implement testing for infectious diseases and is frequently the single major contributor to clinical trials to improve blood safety. Providing life-saving blood and blood products to patients is a key component of the Red Cross mission to help people in times of emergency and disasters.
