Yes, if the donor is blood type O-.


Since blood type O- is antigen non-reactive (it lacks the antibodies for A, B or D [or Rh]), it can be transfused into any individual in need of a blood transfusion.

Blood type O+, however, would react if transfused into an individual who is blood type A- or B-. The presence of Antigen D (the Rh factor) would cause antibodies in the recipient to clump and destroy the infused blood.
