Normal TSH levels are considered to be anywhere between 0.4 to 4.0 mIU/L. These levels indicate that there is no thyroid dysfunction present. Individuals who are undergoing treatment for either hypothyroidism or hyperthyroidism should have TSH levels of 0.5 to 3.0 mIU/L.
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. That is because the reference range is what determines -- for the majority of physicians -- whether or not a thyroid disease or condition is even diagnosed at all, much less treated, and when diagnosed, how it is treated.
