Any group of blood can become a universal donor, the key is in some enzymes. These enzymes remove the red blood cell antigens from the blood groups A, B, and AB, so that the immune system of the receptor does not attack the blood it has just introduced, regardless of its blood group.

The universal donor is group O: it has neither A nor B antigens, so the receptor antibodies do not consider it strange. Groups A, B and AB have antigens A and B. The obstacle to donating your blood to any receptor is the antigen. Enzymes have been found to remove these antigens. After testing with two thousand five hundred extracts of bacteria and fungi, antigens A and B have an effective enzyme.

This is an international study that explains that they are probably used in very special cases, especially in those in which a patient introduces a wrong blood group as a remedy.
