At one time, type O negative blood was considered the universal blood donor type. This implied that anyone — regardless of blood type — could receive type O negative blood without risking a transfusion reaction. However, even type O negative blood may have antibodies that cause serious reactions during a transfusion.

Ideally, blood transfusions are done with donated blood that's an exact match for type and Rh factor. Even then, small samples of the recipient's and donor's blood are mixed to check compatibility in a process known as crossmatching. In an emergency, however, type O negative red blood cells may be given to anyone — especially if the situation is life-threatening or the matching blood type is in short supply.

Similarly, the blood group AB- is said to be the universal recipient as it is possible for the person of AB- group to receive blood from any blood group in a condition of extreme emergency and necessity.
