Concept:A person with blood group
AB can donate blood only to another
AB recipient because their red cells carry both A and B antigens.
Explanation:In transfusion, the donor blood must be compatible with the recipient's plasma antibodies.
Blood group
AB has no anti-A or anti-B antibodies, so an
AB person can receive from any group.
However, the father is the donor and has blood group
AB.
His blood contains both A and B antigens on the red blood cells.
If the victim had group A, B, or O, their plasma would contain antibodies that attack these antigens.
Therefore, a successful transfusion from an
AB donor is possible only if the recipient is also blood group
AB.

AB
