A Person Who Has Anti-A and Anti-B Serum Antibodies Will

Question

A person who has anti-A and anti-B serum antibodies will have blood Type
A)A.
B)B.
C)AB.
D)O.
E)Rh.

Accepted Answer

A person who has anti-A and anti-B serum antibodies means that their blood contains antibodies against both A and B antigens, which are found on the surface of red blood cells. This suggests that they do not have A or B antigens on their own red blood cells and therefore have blood type O, since this blood type lacks both A and B antigens.
