1. BLOOD TYPING LAB

2. GLYCOPROTEINS ON SURFACE OF CELLS DETERMINE BLOOD TYPE

3. PROTEINS that the immune system sees as “NOT SELF” are called ANTIGENS
The immune system makes ANTIBODIES that MATCH each antigen it is exposed to

4. ANTIBODIES bind to ANTIGENS and
cause them to CLUMP TOGETHER (= AGGLUTINATION)

5. BLOOD TESTING LAB Person with A type blood makes ANTIBODIES TO B
Person with B type blood makes ANTIBODIES TO A
Person with O type blood makes ANTIBODIES TO A & B

6. FOR EACH PATIENT
Add 5 drops of PATIENT BLOOD into each well in the test plate.

7. FOR EACH PATIENT
Add 3 drops of ANTI-SERUM (contains ANTIBODIES) into the correctly labeled well in the test plate.
Stir for 10 seconds.

8. YOU CAN’T SEE WHAT GLYCOPROTEINS A CELL HAS
YOU CAN’T SEE WHAT GLYCOPROTEINS A CELL HAS BUT YOU CAN SEE HOW IT REACTS TO THE ANTIBODIES IN THE ANTI-SERUM.
