Blood Typing Lab (Page 2 of 4) in pdf

Blood Typing Lab:

Background: There are protein markers, called antigens, on the surface of red blood cells. You inherit these proteins,

which define your blood type, from your parents. Blood type is particularly important when people give or receive blood

for transfusions.

The immune system uses different types of proteins to fight off foreign cells. Antibodies are one of these types of

proteins. Antibodies might cause foreign cells, such as foreign red blood cells, to clump together. If you receive blood

with a protein marker different from your own, your immune system will use antibodies as part of its attack against the

foreign blood cells. The antibodies will cause the red blood cells to clump together. Blood cannot flow through the

vessels, and death can result.

There are two protein markers, A and B, and four blood groups, A, B, AB, and O, known as the ABO blood group. Type O

blood has no protein markers and can be donated to a person with any other blood type. A person with Type O blood

however, can only accept Type O blood.

Before a patient receives a transfusion, blood must be matched for both the ABO group and the Rh group.
