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 B

Type O

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:

1.Their blood type.

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

Erthyroblastosis fetalis

How are blood types determined?

By genetics . . .

A AA, AO

B BB, BO
