Question

If a donor has blood type AB+, what blood type(s) could receive the blood safely?

A) AB+
B) AB+, A+, B+, O+
C) AB+, O-
D) All blood types

Answer 1

A donor with blood type AB+ can only donate blood safely to individuals with the AB+ blood type due to the presence of A, B, and Rh antigens.

Step-by-step explanation:

If a donor has blood type AB+, the blood types that could receive the blood safely are limited to those with AB positive. Blood type AB contains both A and B antigens on the surface of erythrocytes but does not produce anti-A or anti-B antibodies, which makes it compatible with any ABO blood type. However, since AB+ blood also contains the Rh antigen, it can only be donated to individuals who have the same Rh factor to prevent Rh incompatibility reactions.
