Universal recipient blood group

The Universal blood recipient would be somebody who is AB+. This is because they carry both A and B blood types and have a positive Rh factor. This means they can receive A, B, or O blood types of any Rh factor.

On the other hand, a universal donor would be anyone with Type O, Rh negative blood, (a.k.a. O- or O-Neg). Just about anybody can receive O-neg without risking a serious reaction, which is why it is in high-demand in trauma situations where the patient might need stat blood replacement, but there isn't enough time to type and crossmatch.
