the blood group o does not have any antigen for other blood groups so it does not cause any immunological problem that is why it can transfuse universally. Donors of Blood group O were always referred to as 'universal donors.' Today, because of new research and a better understanding of the complex issues regarding immune reaction related to incompatible donor Blood cells, type O Blood is no longer automatically seen as being suitable in most every case.
Because it has A, B and O antigen.
Yes, A person having O +ve blood group is universal donor
Type O negative.
No it is not..The blood group is O negative.
O negative is the universal donor because when O+ve blood group is transfused to -ve blood group recipient, antibodies are produced which causes hemolysis of Rh +ve labelled blood cells. When O-ve blood is transfused to Rh +ve recipient, no antibodies are produced as donor blood has no Rh factor present on blood cells, so no transfusion reaction occurs. Thus, O -ve is universal donor.
Universal donor
O Rh- is the universal donor and AB Rh- is the universal recipient of all blood types.
O Rh- is the universal donor and AB Rh- is the universal recipient of all blood types.
A blood group 'O' person is called a Universal Donor from sue b :-)
Group O is the universal donor. The downside for people with type O blood is that although their blood can go to anyone with any type (A,B, or O), they can only receive type O for themselves. Luckily, O is common.
No-one because it is a universal blood donor. :)
blood group O because it have no antigen.
O plus is called universal blood donor. Because O plus blood has anti A and anti B antibody. So it will not react with any blood group.
