The 3 tests in this panel

What each one measures and the range labs usually print for adults. Ranges differ a little between labs, so the range on your own report is the one your result is judged against.

  • ABO Blood Group

    Your ABO blood group (A, B, AB or O), set by markers on your red blood cells. It stays the same for life and matters for blood transfusions and pregnancy.

  • Rh (D) Type

    Shows whether your red blood cells carry the Rh (D) protein: positive if they do, negative if not. It matters for transfusions and pregnancy.

  • Red Cell Antibody Screen (Indirect Coombs)

    A blood-bank test that checks whether your plasma has antibodies to red blood cell types you don't have. It is routine in pregnancy and before transfusions.
