Theoretically It is Appropriate to Give O- Blood to an AB

Question

Theoretically it is appropriate to give O- blood to an AB+ recipient.

Accepted Answer

O- blood is a universal donor and does not contain any antigens that would cause a reaction in the recipient. AB+ blood is a universal recipient and can receive any blood type without a negative reaction. Therefore, it is safe to give O- blood to an AB+ recipient. However, this is not always the preferred choice as it does not contain all the necessary antigens and may not provide optimal health benefits for the recipient.
