because it have no antigen.
O+ :is a universal donor
Type O negative.
Type O negative blood is a universal donor blood type. In normal circumstances, anyone can receive type O negative blood in a transfusion. When it comes to plasma donation, type AB positive is a universal donor.
Blood type O-
The universal donor blood type is O negative. This blood type can be given to individuals of any blood type. The universal receiver blood type is AB positive. This blood type can receive blood from individuals of any blood type.
The blood type that is theoretically considered the universal donor is type O. Type O blood does not have any antigens, therefore it is compatible with any blood type.
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.
Blood type O is the universal donor.
Yes, A person having O +ve blood group is universal donor
No. O is the universal donor.
