Does a donor need to have the same blood group as the patient?

For blood stem cell transplants, what matters is the best possible match between the tissue characteristics from the donor and patient.

Blood groups are not so important.

A perfect match is very complicated to find and much like looking for a needle in a haystack. When blood stem cells are transplanted, the recipient acquires the same blood group as the donor.

At most, your blood group would be an additional factor in your selection.
