Which blood group antigens are tested with the ABO blood group test?

• A. A, B, or O
• B. AB, AO, or BO
• C. A only
• D. O only

Answer: (A)

The ABO blood group test is designed to identify the presence of specific antigens on the surface of red blood cells. The antigens include A, B, and O. In this context, A represents the presence of A antigens, B represents the presence of B antigens, and O indicates the absence of A and B antigens. The ABO system classifies blood types accordingly into A, B, AB, or O, depending on which antigens are present or absent. When performing the ABO blood group test, the main focus is on determining if A and/or B antigens are present, which is why the answer identifies A, B, or O as the relevant antigens. This classification helps in ensuring safe blood transfusions and can prevent serious transfusion reactions. The alternative choices, which include various combinations and singular types, do not accurately reflect the primary antigens involved in the ABO blood grouping.
