There has been an accident and three patients are brought in for transfusions. Do you have the know-how to dispense blood from the available bags or will you screw up and cause agglutination? Play the flash game here.
By the way, this is strictly for bio textbooks. In hospitals, whole blood (plasma + cells) transfusions are rarely done. Transfusions are mostly packed RBC’s, platelets (no antigens), or plasma. Blood is carefully cross-matched to avoid incompatibilities.
