Blood Groups: Universal Donors & Recipients — NEET Biology

✅ Asked in NEET 2021
📖 NCERT Source

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'.

How NTA Uses This Concept

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.
