Blood type AB is considered the universal donor. True or False?

Blood type AB is not considered the universal donor; in fact, type O is recognized as the universal donor. Individuals with type O blood can donate to any other blood type because their red blood cells lack A and B antigens on the surface. This absence means that there is no risk of immune reaction from the recipient's body, which would occur if A or B antigens were present on the donor cells and were incompatible with the recipient's blood type.

Conversely, individuals with type AB blood do not have anti-A or anti-B antibodies, which allows them to receive blood from anyone (making them the universal recipient), but they can only donate to other AB individuals without risking an immune response. Thus, the notion that type AB blood is the universal donor is incorrect.
