Blood transfusions in the Rh blood group system:

Rh-positive blood group can be transfused to the Rh-positive recipient because the recipient's blood already has Rh-antigens and it will not produce anti-Rh antibodies Rh-negative blood group can be transfused to Rh-negative because the donor's blood does not have Rh-antigen and the so recipient's blood will not produce anti-Rh antibody If an Rh-negative person receives Rh-positive blood, he she will produce antibodies against Rh-factors. Rh-negative blood can be transfused to an Rh-positive recipient, only if the donor's blood (Rh-negative) has never been exposed to Rh-antigens….
