My daughter is getting a bone marrow transplant. Her entire DNA will change to become the donors. Does she have to get re-baptized?
No, she does not need to be baptized again. God knows who she is. She is in our prayers.
Further; a physician wrote in concerning the fear of losing one's DNA: "As a physician I would like her to know that this is NOT the case. Her dtr's white blood cells will indeed carry the donor's DNA but all the other cells in her body will always carry her own DNA."
