Blood transfusion: The transfer of blood or blood components from one person (the donor) into the bloodstream of another person (the recipient). Blood transfusion may be done as a lifesaving maneuver to replace blood cells or blood products lost through bleeding or due to depression of the bone marrow. Transfusion of one's own blood (autologous) is the safest method but requires advanced planning, and not all patients are eligible for it. Directed donor blood allows the patient to receive blood from known donors.
What is a blood transfusion reaction? A blood transfusion reaction is a harmful immune system response to donor blood. Reactions can occur right away or much later, and can be mild or severe. Your immune system can react to anything in the donor blood. One of the most serious reactions is called ABO incompatibility. The 4 main blood types are A, B, O, and AB. Your immune system will try to destroy donor cells that are the wrong type for you. Another reaction happens when you are allergic to something in the donor blood. Allergic reactions are usually mild but can become a life-threatening reaction called anaphylaxis.
