2. Blood Types
ABO blood groups are due to protein antigens (markers) on the red blood cells
Rh+ and - blood types are due to a different protein (Rh factor)

3. Immune system produces antibodies against blood antigens, causing clotting of the blood

5. Blood Typing
To determine your blood type, antiserum containing antibodies are added to the blood sample
