to determine the utility of laboratory tests for diagnosing thyroid disease in the hospitalized elderly , we measured serum thyroid-stimulating hormone ( tsh ) , thyroxine ( t4 ) , free thyroxine index ( ft4i ) , triiodothyronine ( t3 ) , and free triiodothyronine index ( ft3i ) in 125 geriatric inpatients , mostly men , and compared the results to those in elderly ambulatory patients .
