The Blood Type Test (ABO, Rh) determines your blood type. It identifies your blood group (A, B, AB, or O) and whether your blood is Rh positive or Rh negative.
- People whose red blood cells have A antigens are in blood group A.
- Those with B antigens are in group B.
- Those with both A and B antigens are in group AB.
- Lastly, those who do not have either of these markers are in blood group O.
