Blood Group & Antibody

Test for blood type & transfusion

SHORTCUTS Procedure Results FAQ
This test tells you which blood group you have (A, B, AB, or O) and is useful for those who need a transfusion or want to give blood.

The blood group and antibody test determines your blood type, and it is done by detecting certain proteins in your red blood cells, called antigens. This test allows you to safely donate blood, or receive a blood transfusion or transplant, because the blood types must match in order to avoid the immune system attacking the donated cells or transplant.

The test also checks for the presence of Rh factor in your red blood cells. Blood types are usually hereditary, and are classified using the ABO system (your result will be Type A, Type B, Type AB, or Type O).

Blood typing is also important during pregnancy, to ensure that the mother’s immune system will not react against the foetus. Testing can prevent anaemia and jaundice in new-borns.


Preparing for test

Please arrive for this test well-hydrated, to make the procedure easier.

During the test

This test is a simple blood test. A needle is inserted into a vein, usually on the inner arm near the elbow, and a small amount of blood is drawn. You may feel a pricking or scratching sensation.

You will receive the results as a PDF attachment as soon as the laboratory makes them available.


What do the different blood typing results mean?

If you have blood type A, it means that A antigens were found on your red blood cells, with anti-B antibodies in your plasma. With blood type B, you have B antigens, with anti-A antibodies. Blood type O has no antigens, and both anti-A and anti-B antibodies. Blood type AB has both A and B antigens, and no antibodies.

What happens if I receive a transfusion of the wrong blood group?

An incorrect blood type match can be fatal, causing an immune response in which the antibodies attack the donation blood cells. The only safe blood group that can be given to any recipient is type O.

Why is a blood group test recommended in pregnancy?

A pregnant woman will be given a blood test to determine her RhD status. If the mother is RhD negative, but the child is RhD positive due to blood inherited from the father, it can lead to complications. If this is caught, it can be treated, lowering the risk of problems.
