      1. Physiologic Anemia of Infancy
        1. Requires no work-up unless below expected levels
      2. Hemolytic Anemia
        1. Hemolytic Disease of the Newborn
        2. Glucose-6-Phosphate Dehydrogenase Deficiency (G6PD)
          1. X-Linked Anemia (consider in male children)
        3. Pyruvate Kinase Deficiency
          1. Results in chronic Hemolytic Anemia
    3. Macrocytic Anemia (uncommon in children)
      1. Folate Deficiency
        1. Inadequate intake of human or cow's milk

    3. Hemoglobin disorders (e.g. Thalassemia, Sick Cell Disease)
    4. RBC Enzyme deficits (e.g. G6PD Deficiency, Pyruvate Kinase deficiency)
    5. RBC membrane Deficits (e.g. Spherocytosis, elliptocytosis)
    6. Acquired Hemolytic Anemia (e.g. Hemolytic Uremic Syndrome, drug-induced Hemolysis)
    7. Transient Erythroblastopenia of childhood
