Question

Persons with 'AB' blood group are called as "Universal recipients". This is due to :

Accepted Answer

Correct Answer: A — Absence of antibodies, anti-A and anti-B, in plasmaStep-by-step Solution:Individuals with blood group AB have both A and B antigens on the surface of their RBCs, but their plasma contains neither anti-A nor anti-B antibodies. Since agglutination (clumping) occurs only when antibodies in the recipient's plasma react with antigens on the donor's RBCs, AB individuals can receive blood from any ABO blood group (A, B, AB, or O) without agglutination. This is why AB individuals are called universal recipients.Why other options are incorrect:B: AB individuals have both A and B antigens on their RBCs. Absence of antigens describes group O individuals.C: Antigens are present on RBC surface, not in plasma.D: Antibodies are present in plasma, not on RBC surface; and AB group has no plasma antibodies.Key Concept: ABO blood group system: Group O = universal donor (no antigens, both antibodies); Group AB = universal recipient (both antigens, no antibodies). Agglutination occurs when plasma antibodies react with RBC antigens.
