Blood Transfusions
Blood types become very important when a blood transfusion is necessary.
In a blood transfusion, a patient must receive a blood type that is compatible with his or her own
blood type—that is, the donated blood must be accepted by the patient's own blood.
If the blood types are not compatible, red blood cells will clump together, making clots
that can block blood vessels and cause death.
Type O– blood is considered the “universal donor” because it can be donated to people of
any blood type. Type AB+ blood is considered the “universal recipient” because people with this
type can receive any blood type.
Blood Types
Human blood is grouped into four types: A, B, AB, and O. Each letter refers to a kind of antigen,
or protein, on the surface of red blood cells.
For example, the surface of red blood cells in Type A blood has antigens known as A-antigens.
