There is more to the TSH than a number

[摘要] In a previous issue of the Journal, an article1 and commentary2 discussedthe effi ciency and suffi ciency of using only the thyroid-stimulating hormone (TSH) level to monitor the dosing of thyroid replacement therapyin patients with primary hypothyroidism. The validity of the TSH measurement inthat setting was emphasized. Yet in the current issue of the Journal, Azim and Nasr(page 101) summarize some of the controversies in managing subclinical hypothyroidism (an elevated TSH in the setting of a normal level of endogenous free thyroxine,T4), and some of the controversies relate to foibles in interpreting the measured levelof TSH.
