Question

A certain road accident patient with unknown blood group needs immediate blood transfusion. His one doctor friend at once offers his blood. What was the blood group of the donor?

• A. Blood group B
• B. Blood group AB
• C. Blood group O
• D. Blood group A

Answer 1

The correct option is C Blood group O

If blood is to be donated to a person of unknown blood group in emergencies, then the blood group is of 'O' type as the RBCs of this blood group do not have antigens and hence, do not attract any antibody reaction from the plasma of the recipient.

So, the correct answer is 'Blood group O'.
