Detailed explanation-1: -Blood group O individuals do not have either A or B antigens on the surface of their RBCs and hence can donate blood to individuals of any ABO blood group.
Detailed explanation-2: -For example, anti-A attacks red cells of Group A or AB. Anti-B attacks red cells of Group B or AB. If ABO incompatible red cells are transfused, red cell haemolysis can occur. For example if group A red cells are infused into a recipient who is group O, the recipient’s anti-A antibodies bind to the transfused cells.
Detailed explanation-3: -For emergency transfusions, blood group type O negative blood is the variety of blood that has the lowest risk of causing serious reactions for most people who receive it. Because of this, it’s sometimes called the universal blood donor type.
Detailed explanation-4: -If you have type A blood, you cannot get either type B or AB red blood cells. If you have type B blood, you cannot get type A or AB red blood cells. If you have type AB blood, you can get transfusions of O, A, B, or AB red blood cells.
Detailed explanation-5: -Group AB can donate to other AB’s but can receive from all others. Group B can donate red blood cells to B’s and AB’s. Group A can donate red blood cells to A’s and AB’s. Group O can donate red blood cells to anybody.
