As of late 2016, at most laboratories in the U.S., the official reference range for the Thyroid Stimulating Hormone (TSH) blood test runs from approximately 0.5 to 4.5/5.0. The reference range -- also sometimes called the normal range -- is an important part of the complete picture of thyroid diagnosis and treatment. In fact,the entire TSH test as diagnostic and management tool depends on this validity.
The normal levels of the thyroid hormone in men as well as women are deemed to be between 0.5 mIU/L to 4.5 mIU/L. The normal levels of the thyroid hormone in infants are deemed to be between 3 mIU/L to 18 mIU/L. The abbreviation mlU/L represents milli-international units per liter.
