What determines blood transfusion compatibility?

Compatibility testing is performed to determine if a particular unit of blood can be transfused safely into a certain patient. This includes ABO-Rh blood typing (see above), antibody screening (for unexpected red blood cell antibodies that could cause problem in the recipient), and cross-matching.

Can you get a blood transfusion from anyone?

Blood Types About 40\% of people have type O blood, which is safe to give almost anyone in a transfusion. If you have type O blood, you’re called a universal donor. If you have type AB blood, you can receive any type of blood and you’re called a universal recipient.
