Blood Transfusion

Blood transfusion is a medical treatment to replace blood or portions of the blood lost through injury, surgery, or disease.

During a transfusion, people normally receive only the parts of blood needed to treat their conditions. Whole blood is now rarely given as a transfusion.

Blood for transfusions may come from anonymous donors, or a person can bank his or her own blood in preparation for surgery.
