ABO Grouping, Blood Type, A,B,O & Rh factor
Test Results & Interpretations
Overview of Blood Grouping
This test determines your blood group. Your blood type is determined by what kind of antigens your red blood cells have on their surface. The ABO blood typing system groups your blood into one of the four categories: Type A has the A antigen, Type B has the B antigen, Type AB has both A and B antigens while type O has no antigens on the surface. Another factor called Rh is also present on the surface which determines whether blood group is Rh positive or negative.
Why Get Tested
- When you need blood transfusion which may be required in case of severe anemia, bleeding after surgery, excessive blood loss, bleeding disorders
- When you donate blood at a collection facility
- When you become a candidate for an organ, tissue or bone marrow transplant or when you wish to become a donor for transplantation
- During pregnancy to determine the risk of Rh incompatibility
- No special preparation required
What Results of Blood Grouping mean?
