Why Is Ab The Universal Recipient
People with type AB blood can receive any other types of blood.
Why Is O Negative The Universal Donor
Those with type O- blood are called universal donors because their donated red cells have no A, B or Rh antigens and can therefore be safely given to people of any other kind.
Why Is Type O Rh-Negative The “Universal Donor”?
O negative is the universal donor because there are absolutely no proteins on its RBCs, which means that anyone can receive this blood without suffering rejection.
