DIRECTIONS:
1.) Note in the boxes provided below the antibodies (not antigens) found in each blood type, as well
as whether or not the blood type in the first column would react to mixing with the blood types
in the horizontal second row. I.e. if someone with type O blood received type O blood in a
transfusion, would there be a reaction or not? If yes, write: Reaction; If no, write: No Reaction.
2.) Draw or describe the antigenic reaction that you have indicated would take place in some of the
