Which blood type is known as the universal recipient for packed red blood cell transfusions in the ABO system?
Answer and explanation
Correct answer: C. AB positive
- Step 1: Individuals with AB+ blood express both A and B antigens as well as the Rh(D) antigen on red cells. Step 2. Their plasma contains no anti-A, anti-B, or anti-Rh antibodies, allowing them to safely receive RBCs of any blood group. Answer: AB positive (AB+). Why not the others: O negative is the universal donor; O positive can only receive O type blood; A positive contains anti-B antibodies.
