1. Use this case and image for the next three questions. A 12-year-old boy presents to the clinic with persistent fatigue, easy bruising, and occasional nosebleeds for the past 2 weeks. He has progressive fatigue for a month. His past medical history is unremarkable. His vital signs are within normal range. Physical examination reveals pale skin and conjunctiva without jaundice. Numerous petechiae are seen on his extremities. A few cervical lymph nodes are palpated. His CBC reveals a hemoglobin of 8.5 g/dL (11.5-12.8 g/dL), WBC count of 54 x 109/L (4.5-10 x 109/L), platelet count of 75 x 109/L (160-320 x 109/L). An image of his peripheral blood smear is shown. What test should be performed next for diagnosis?
