Comments:

This test detects the presence of unexpected antibodies (allo- or auto-) against red blood cell antigens. Patient plasma or serum is tested against a cell panel that contains common red cell antigens. The majority of clinically significant red blood cell alloantibodies are detected by this technique. If positive, an extended cell panel (antibody identification) will be performed to determine red blood cell antigen specificity.
