During blood transfusion, agglutination may occur as a result of the reaction between ____________
A. similar antigens and antibodies B. contrasting antigens and antibodies C. two different antigens D. two different antibodies
Correct Answer: B
Explanation
During blood transfusion, it must be ensured that the antigen in the blood of the donor agrees with the antibody in the blood of the recipient, otherwise agglutination occurs. For instance, if a person with blood group A is given blood type B, agglutination will result because blood A has antibody - B which will antagonize the antigen
