| ABO, Rh and antibody screen These ABO, Rh, and antibody screen results were obtained by the TS using the blood specimen that was collected prior to starting the emergency transfusion with O Rh-negative RBCs.

| Antibody identification (2 weeks post-transfusion) Fortunately, the patient's condition stabilized and additional transfusions were not required. Two weeks later, new patient specimens were drawn for antibody studies.
