In blood transfusion, it is necessary that the kind or the type of blood to be transfused should be matched with the type of blood of the receiving person. Otherwise, the RBC of the donor blood will stick to each other and block the passage of blood vessels of the receiver leading to death. Hence, it is necessary to know the blood groups before transfusion of blood.
