Quizplus · Accepted Answer

A blood urea nitrogen level >30 mg/dL suggests renal impairment, which can lead to anemia of chronic disease. The elevated serum ferritin level also supports this diagnosis. Iron deficiency anemia would typically present with a low serum ferritin level. Diamond-Blackfan anemia and Fanconi's syndrome are both rare genetic conditions that would not be supported by the laboratory findings provided.
