The people with O -ve blood group are called “Universal Donors” as their blood lacks A and B antigens and also is devoid of the Rhesus factor. So, anyone can receive O –ve blood. On the other hand, people with AB blood group are called “Universal Recipient” as their blood lacks A and B antibodies to fight the A and B antigens; therefore, one with the AB blood group can receive blood from any other blood groups.
