During the 256th National Meeting & Exposition of the American Chemical Society, researchers from the University of British Columbia describe they may have found a way to convert blood group into blood type O. Researchers believe using a bacterial enzyme will turn any blood into type O. The bacteria enzyme is from the human gut. To convert any blood types AB, A, B, into O, the markers or antigens from these types of blood will need to remove. By removing these antigens, all blood will be compatible. This is just a theory right now. Currently, researchers are continuing to work on this new idea. So far, they had gotten outstanding results from samples of human feces.
This idea is very calm and astonishment. Right now, there are four basic types of blood groups. There are AB, A, B, and O. Each of these blood groups has different antigens. Blood A has A antigens and can only get it A blood, blood AB has A antigens and B antigens and can receive any type. Blood B has B antigens and can only get B blood.
On the other hand, blood O has no antigens but can give to any of the blood groups. Also, blood O can only receive from O. If in the future, this succeeds, everyone will no longer need to wait for blood donations. All blood will be compatible with each other.
