What I am concerned about. He was not totally drained of his own blood. Therefore they had to do something either on purpose, on accident or something to keep him from going into hemolytic shock. Meaning his normal bloodtype clumping together with the new bloodtype of B. There was DNA changes done. Had to have been.

Some blood types are compatable with others. For instance if the kid was AB before the change he is compatibile with all blood types. It just depends on the original blood type and and the new blood type.

For one, his own bone marrow would have been killed off by chemotherapy. Before they give a transplant, they get just about every patient white blood cell killed off which means antibodies to the new cells aren't made and there won't be any hemolytic reaction. The new cells take over and they will make antibodies against the the old blood type if it tries to come back. In bone marrow transplants, it's the HLA match that matters more than blood group and Rh.
