Biology 2014 JAMB Past Questions - Question 46: An individual with blood group AB can receive blood from those in blood group(s)

Correct Answer

A

Explanation

The individual receives blood from all the groups. He has only antigens on the surface of his red blood cells without any complimentary antibodies on his plasma. In blood transfusion, what is. actually considered is the antigens on the surface of incoming red blood cells because the antibody is removed along with the .plasma during centrifugation. Blood group AB has no antibodies in its plasma and therefore there is no reaction or agglutination when blood from other groups , is transfused to a recipient of blood group AB. Blood groups A, B and O Piave antibodies in their plasma which are usually removed before transfusion is effected. However, mild agglutination occurs in each case but the large volume of the blood of the recipient AB dilutes the agglutination
