Question

A person with blood group who can receive blood from any of the four
blood groups.​

Answer 1

Answer:

Answer 2

Explanation:

Group O is often referred to as the universal red cell donor. Group AB individuals have neither anti-A nor anti-B antibodies in their plasma. Group AB plasma can therefore be given to patients of any ABO blood group and is often referred to as the universal plasma donor.
