What is the universal blood type?
Only ‘O’ Negative redcells can be given to all other blood groups. It is not available most of the times. Hence, universal donation is not practiced very frequently. Moreover, other specific blood groups are mostly available for transfusion. O positive red cells can be given to other Rh positive groups.
Type O negative, occurring in about 7% of the U.S. population, is the universal donor blood type. O negative blood can be transfused to patients with any other blood type. AB positive, which occurs in only 2.5% of the U.S. population, is the universal recipient. Patients with AB positive blood can receive blood from any other blood type.
