Abstract

According to the transfusion guidelines, type O RBC is the best choice for emergency transfusions if the recipient’s ABO group is unknown. If the recipient’s ABO group is confirmed after pre-transfusion tests, ABO identical and ABO compatible (but non-identical) RBC is the second-best choice in that order. However, non-transfusion medicine physicians have a misconception that type O RBCs are always the second best for patients in all emergency/massive transfusions. The author suggests the use of optimal ABO non-identical but compatible RBC components in emergency/massive transfusions, especially for AB+ recipients.
