In the case of a child with microcytic anemia, the most appropriate next step is to initiate oral iron therapy. Microcytic anemia commonly indicates iron deficiency, especially in a pediatric population. When evaluating a child with this condition, it is crucial to begin treatment by addressing the most likely underlying cause, which in this scenario is iron deficiency anemia.

Oral iron supplements are effective in replenishing iron stores and improving hemoglobin levels. In most cases, it is advised to perform a trial of oral iron for several weeks to ascertain improvement in the child's hemoglobin levels and overall health. Monitoring should follow to assess the response to iron supplementation.

While hemoglobin electrophoresis can provide insights into different types of anemia, such as thalassemia or sickle cell disease, initiating this test does not address the immediate need for treatment. Vitamin B12 supplementation may be relevant in cases of macrocytic anemia caused by deficiencies in B12, which is not related to microcytic anemia. Referral to a hematology specialist is also more appropriate if the microcytic anemia does not improve with iron therapy or if there are signs indicating more complex hematologic disorders, but it is not the first step in routine management.
