2024 Re-NEET Body Fluids and CirculationABO and Rh blood group systems Medium Question 9 of 83 in Body Fluids and Circulation

A person with blood group $ARh^-$ can receive the blood transfusion from which of the following types? A. $BRh^-$ B. $ABRh^-$ C. $ORh^-$ D. $ARh^-$ E. $ARh^+$. Choose the correct answer from the options given below:

A D and E only
B D only
C A and B only
D C and D only

The answer is D.

Solution

A recipient with $Rh^-$ blood cannot receive $Rh^+$ blood (would trigger an immune response against the Rh antigen). Also, as an A blood group individual has anti-B antibodies in plasma, they cannot receive blood containing the B antigen (B or AB groups). Hence the donor can only be $O\,Rh^-$ (universal donor, C) or $A\,Rh^-$ (D) — so the answer is C and D only.
