Capillary zone electrophoresis of the patient’s hemoglobin. CE shows the hemoglobin variant eluting with normal hemoglobins. Note peaks corresponding to Hb Shepherds Bush (6.5% of total, zone 10), HbA (89.6%, zone 9), HbF (0.3%, zone 7), HbA2 (3.2%, zone 3) and hemoglobin breakdown products (0.4%, zone 2). This chromatogram was obtained after a transfusion following a parvovirus infection described later accounting for the small amount of her native hemoglobin compared to HbA.
