Which blood type is considered the universal donor? Why can this blood type be given to all other blood types? A.O- is considered the universal donor because this blood type has none of the A, B, and Rh antigens on the surface of its erythrocytes. Therefore, it cannot bind to any recipient's antibodies. B.O+ is considered the universal donor because it lacks the A and B antigens. For this reason, it will not react to a recipient's antibodies. C.AB+ is considered the universal donor because this blood type has none of the A, B, and Rh antigens on the surface of its erythrocytes. Therefore, it cannot bind to any recipient's antibodies. D.AB- is considered the universal donor because this blood type has none of the A, B, and Rh antigens on the surface of its erythrocytes. Therefore, it cannot bind to any recipient's antibodies.
