Question

Sheena has blood group O+ and Veena has AB+. Whose blood would be useful if it has to be transfused into an accident victim of unknown blood group and why?

Answer 1

Answer:

In case of blood transfusion to a person with unknown blood group sheena with blood group O positive is best option.

This is because O group blood doesn't contain any antigens either A or B so can be donated to any one.

Hence people with O blood group are considered as universal donars.
