An elevated ferritin level was discovered during an anemia evaluation in a 46-year-old man with inflammatory arthritis. The patient reported pain in multiple joints for which he took indomethacin. He also consumed 2 alcoholic beverages daily. His mother had inflammatory arthritis and his sister had lupus. On physical examination, the patient’s blood pressure was 148/82 mm Hg, pulse was 92/min, and body mass index was 28. The liver was 7.0 cm and slightly firm. He was anicteric with no stigmata of chronic liver disease and the spleen was not palpable. Physical examination findings were otherwise unremarkable. The results of laboratory tests are shown in the Table.
