What blood types can be transfused to a person with blood type AB?

AB blood type has a relatively unique compatibility in blood transfusion, as it can accept A, B, AB, and O blood types. This is because AB red blood cells carry both A and B antigens on their surface, while the plasma contains neither anti-A nor anti-B antibodies. Therefore, blood from all four blood types can be safely transfused into AB recipients without causing severe transfusion reactions. However, in actual clinical practice, the principle of matching blood types should still be followed; that is, AB blood type patients should primarily receive AB blood. Only in emergency situations, when supplies of other blood types are insufficient, should blood from other types be considered, with strict control of transfusion rate and volume to ensure transfusion safety. Additionally, Rh blood group compatibility must also be considered to avoid transfusion reactions caused by Rh incompatibility.
