Write answer in between .Q:A 15-year-old African American boy presents to a pediatrician with complaints of yellow discoloration of the sclerae for the last 3 days. His mother informs the pediatrician that the boy developed prolonged jaundice during the neonatal period. On physical examination, vital signs are stable and general examination shows mild icterus and pallor. Examination of the abdomen suggests mild splenomegaly. Laboratory results are as follows:Hemoglobin 9.9 gdLTotal leukocyte count 7,500mm3Platelet count 320,000mm3Reticulocyte count 5Mean corpuscular hemoglobin 27.7 pgcellMean corpuscular hemoglobin concentration 32 gdLMean corpuscular volume 84 μm3Serum total bilirubin 4.2 mgdLSerum direct bilirubin 0.3 mgdLCoombs test NegativePeripheral smear shows polychromasia, blister cells, and Heinz bodies. An abdominal ultrasonogram shows the presence of gallstones. Which of the following tests is most likely to be useful in diagnosing this patient?? A: Glycerol lysis test, B: Methemoglobin reduction test, C: Serum thyroxine, triiodothyronine, and thyroid-stimulating hormone, D: Serum lipoprotein-X level, E: Hepatoiminodiacetic acid scanning,  <response>: This is a clinical case scenario about a 15-year-old African American boy with jaundice and anemia. The key findings are:- Prolonged neonatal jaundice- Icterus and pallor on exam - Mild splenomegaly- Anemia, reticulocytosis, and abnormal RBC morphology on smear - Negative Coombs test- Gallstones on USBased on the history of neonatal jaundice, exam findings of splenomegaly, and anemia with abnormal RBC morphology, this patient likely has an inherited hemolytic anemia like sickle cell disease or G6PD deficiency. The question asks which test would be most useful to diagnose the patient. Options A and B test for hemoglobin abnormalities seen in sickle cell disease. Option C tests thyroid function which is unrelated. Option D tests for cholestasis which does not fit the presentation. Option E evaluates liver function which is not the primary concern.Therefore, options A or B testing hemoglobin abnormalities would be the most useful diagnostic tests in this patient with likely inherited hemolytic anemia.B: Methemoglobin reduction test
