ABO Blood Group System tests exam elaboration
Which of the following distinguishes A1 from A2 blood groups?
A. A2 antigen will not react with anti-A, A1 will react strongly (4+)
B. An A2 person may form anti-A1; and A1 person will not form anti-A1
C. An A1 person may form anti-A2, an A2 person will not form anti-A1
D. A2 antigen will not react with anti-A from nonimmunized donor; A1 will react with any
anti-A -answer- B
The group A1 comprises both A1 and A antigens. Anti-A will react with both A1 - and A2
-positive RBCs. A person who is group A2 may form anti-A1 , but an A1 person will not
form anti-A1 (which would cause autoagglutination).

A Bombay individual does not express A, B, or H antigens; therefore anti-A, B, and H
are formed. Because a Bombay individual has three antibodies, the only compatible
blood must be from another Bombay donor.
