What you will learn today . . .
• There are four blood types: A, B, AB, and O• O blood type is called the “universal donor”
while AB blood type is the “universal recipient”• Your blood cells are marked with antigens
(agglutinogens) that label what blood type they are
• Antibodies (agglutinins) are present in A, B, and O blood types; therefore, the antibodies will attack other blood types by clumping the blood—a reaction called agglutination
Blood Type Lab

Type A
Blood Types have markers called antigens . . .
Red Blood Cells also have antibodies. . .
How does this apply to blood transfusions?
What happens if wrong blood types are mixed?
Agglutination
Let’s play the blood type game…
For each patient record:

2.The types of blood they can safely receive during a transfusion.
