Blood type is determined by the hereditary presence or absence of antigens A and B on red blood cells. Which term describes this blood grouping system?

• A. ABO Blood Group
• B. Rh Blood Group
• C. MNS System
• D. Kell Phenotype

Answer: (A)

Blood type is determined by the hereditary presence or absence of A and B antigens on red blood cells. The term that describes this grouping is the ABO blood group system. In this system, A antigens define type A blood, B antigens define type B blood, both antigens define type AB, and neither antigen defines type O. The ABO system is the primary basis for transfusion compatibility because the immune system can produce antibodies against the A or B antigen if they are not present on a person’s own cells. The Rh system (D antigen) is a separate grouping, and MNS and Kell are different antigen systems, not describing the A and B antigens in this question.
