Blood Groups: Universal Donors & Recipients — NEET Biology
✅ Asked in NEET 2021Persons with 'AB' blood group are called as "Universal recipients". This is due to: (NEET 2021)
Persons with 'AB' blood group are called as "Universal recipients". This is due to: (NEET 2021)
Answer & NCERT explanation
Correct answer: B — Absence of antibodies, anti-A and anti-B, in plasma
AB blood group individuals have both A and B antigens on RBCs but no anti-A or anti-B antibodies in plasma. This allows them to receive blood from any ABO group without antibody-antigen reaction causing agglutination. They are universal recipients due to antibody absence, not antigen presence.

From the above mentioned table it is evident that group 'O' blood can be donated to persons with any other blood group and hence 'O' group individuals are called 'universal donors'. Persons with 'AB' group can accept blood from persons with AB as well as the other groups of blood. Therefore, such persons are called 'universal recipients'.
NTA tests whether students understand why AB blood group individuals are universal recipients while O group individuals are universal donors. The core concept: AB group has both A and B antigens but no anti-A or anti-B antibodies, so their blood won't be rejected by any blood type. Common mistake: Students confuse which group is universal donor vs. recipient—remember O group lacks A and B antigens (can donate to all), while AB group lacks antibodies (can receive from all). Key point: Universal donors lack antigens; universal recipients lack antibodies. This concept appears in transfusion compatibility questions, making it high-priority NEET material.
