Question

    Which blood group is considered the universal blood

    donor?
    A AB Correct Answer Incorrect Answer
    B AB- Correct Answer Incorrect Answer
    C O+ Correct Answer Incorrect Answer
    D O- Correct Answer Incorrect Answer

    Solution

    O- (O negative) is the true universal blood donor type because these red blood cells do not carry any antigens. This allows O- blood to be donated to recipients of any blood group. While O+ (O positive) is sometimes called a universal donor, it cannot be given to Rh-negative individuals.
