The Blood Typing Game

What happens if you get a blood transfusion with the wrong blood type? Even though a patient's own blood type is the first choice for blood transfusions, it's not always available at the blood bank. Try to save some patients' lives and learn about human blood types! (To receive the wrong blood type is life-threatening. In this game allowing three attempts is for learning purpose!)

Who can receive blood from whom?

People can happily receive blood from the same blood type as their own, but they have antibodies against any antigens not found on their own red blood cells. Look at the "Compatible blood chart" below!

ABO blood system
O can only receive blood from: O
A can receive blood from: A and O
B can receive blood from: B and O
AB can receive blood from: AB, A, B and O

Rh blood system
Rh+ can receive blood from: Rh+ and Rh-
Rh- can receive blood from: Rh-


This "Compatible blood chart" refers to blood transfusions with red blood cells.

People with O Rh- blood can only receive O Rh- blood.
People with O Rh+ can receive both O Rh+ and O Rh- blood.
People with blood type AB Rh+ can recieve blood from all blood types and therefore are called Universal receivers.
