Question

Franco is rushed to the hospital after losing blood from a work relates accident. Because he was wearing a medical alert bracelet, the hospital staff knows he has A+ blood.

What specific blood types can he receive?

Answer 1

As said, The guys blood group is A+ implies he has blood that contains A antigen and anti-B antibodies, the blood types that we can give should not contain B antigen which will result in Antigen-Antibody reaction.

So as you know, in ABO grouping, blood groups are names according to the antigen it has in the RBC,

A has A antigen and anti-B antibodies

B has B antigen and anti- A antibodies

AB has both A and B antigen and no antibodies

O has no antigen and has both anti- A and anti-B antibodies..

Rh positive blood group won't be having anti-Rh antibodies.

So the blood being donated should not contain an antigen against which an antibody is present on the recipient's blood..

SO IN FRANCO'S CASE HE CAN RECIEVE ONLY A+ AND O+, O-(universal donor) BLOOD GROUPS.

It can be given as fresh blood, or packed cell.
