Blood cells have antigenic markers on the surface of their cell membranes. People with certain ABO blood antigens can accept a transfusion from some donors, but not from others. Indicate if the following transfusion is likely to result in a transfusion reaction: Donor ABO type: A
Recipient ABO type: A

Quizplus · Accepted Answer

The transfusion would be safe and the donated blood would be compatible with the recipient's blood. The ABO blood group antigens are cell surface markers found on the outer membranes of red blood cells. Incompatibility in these markers can result in transfusion reactions. The four ABO blood groups are Groups A, B, AB, and O. People who have type A blood have the A antigen on the surface of their red blood cells and have circulating antibodies against B antigens in their plasma. People who have type B blood have the B antigen on the surface of their erythrocytes and circulate antibodies against A antigen in their plasma. People with type AB blood have no circulating antibodies against A or B antigens and have both of these antigens on their blood cells. People with type O blood have neither A nor B antigens on their red cells but have antibodies against both of these antigens circulating in their plasma.
Therefore, a person with type A blood can receive a transfusion from another person with type A blood because the transfused blood would have no incompatible antigens.
