Which blood group is a “universal donor”?

Which blood group is a “universal donor”?

  • (A) Group A
  • (B) Group AB
  • (C) Group B
  • (D) Group O negative
Individuals with O negative blood are referred to as universal donors. This is because their red blood cells do not have three things: A antigens, B antigens, and Rh factor (negative). This is why O negative blood can be transfused to patients with blood groups A, B, AB, or O, whether positive or negative.
