Question

Which blood group is called universal donor

Answer 1

With regard to transfusions of packed red blood cells, individuals with type O Rh D negative blood are often called universal donors, and those with type AB Rh D positive blood are called universal recipients; however, these terms are only generally true with respect to possible reactions of the recipient's anti-A.No, the blood type that is referred to as the"Universal Donor" is O negative, not O positive. Antigens are proteins (or glycoproteins) on the surface of red blood cells that can react with the recipient's immune system in such a way that the recipient would be harmed.

Answer 2

O positive is the blood group which is called universal donor.
