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.
1 An under active thyroid presents with a TSH ranging from 2mIU/L or more than that. 2  A TSH level count ranging between 0.5 and 3mIU/L confirms thyroid disorder. 3  The normal TSH range for newborns ranges from between 1 â 39 mIU/L. 4  The normal TSH levels for children ranges from between 0.7 â 6.4 mIU/L.
