Comments:
This test determines the patient's red cell antigen genotype for
common blood groups. A pre- or post-transfusion sample can be used.
The results are often used in the selection of blood for patients with
hemoglobinopathies or multiple antibodies who are likely to receive
chronic transfusions.
