Serum Thyrotropin and Thyroid Hormone Levels in Elderly and Middle‐Aged Euthyroid Persons

Abstract

Euthyroid older persons have about the same levels of serum TSH as younger ones, although older euthyroid women have a slightly lower serum TSH than middle-aged women. We recommend that the normal range of serum TSH in the elderly be considered to be the same as that in healthy middle-aged subjects.
