A complete metabolic panel and complete blood count with manual differential are performed: Total bilirubin 8.4 mg/dL WBC 9,800/mm3 Hemoglobin  6.5 g/dL MCV 82.3 fL Platelet count  465,000/mm3 Reticulocyte 7% Peripheral blood smear shows multiple clumps of elongated and curved cells and erythrocytes with nuclear remnant. The patient's hemoglobin electrophoresis result is pictured below. What is the most likely cause of his condition?   (A) Sickle cell trait   (B) Sickle cell disease   (C) Hemoglobin F   (D) HbC
