Blood Types

By: Amanda Forgione, Dora Konstantopoulos, Eva Primbas, Shannon Wilding

• Some red blood cells have agglutinogens.

• There are several types of blood agglutinogens.

• Blood types are determined by the ABO system.

ABO System

Rhesus Factor (Rh)

• No Rh in blood = negative blood

• Rh found in blood = positive blood

• ABO + Rh system = 8 different blood types

• No ABO agglutinogen + Rh = O positive blood

• Plasma contains antibodies

• Antibodies: act against agglutinogens that they do not already possess

• Agglutinins = antibodies

• Antibodies bind with different agglutinogens in order to neutralize them

Antibodies

TranSfusion

• - A blood transfusion is when a product of blood (usually RBC) is given to another person.

• - Major risk when transfusing blood: Combining an agglutinin and its agglutinogen in the body of the person receiving the blood. This can cause agglutination.

 Blood Compatibility

• - Blood can only receive the agglutinogens they already have.

• - If the blood receives the agglutinogens they don’t have, the recipient’s antibodies will agglutinate with the RBC of the foreign blood.
