The normal TSH reference range: what has changed in the last decade?

Abstract

The current AACE (American Association of Clinical Endocrinologists) and ATA (American Thyroid Association) guidelines recommend to treat patients with persistently elevated TSH GREATER-THAN OR EQUAL TO 10 mIU/l and persistently decreased TSH <0.1 mIU/l. Treatment of mild hyperthyroidism (TSH 0.1-0.4 mIU/l) and mild hypothyroidism (TSH <10 mIU/l) is matter of controversy.
