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.
How to Read the Results. For healthy adults, the normal TSH range is 0.4 - 4.0 milli-international units per liter of blood. This range jumps to 0.5 and 3.0 milli-international units per liter of blood for patients that are being treated for thyroid disorders. If our thyroid hormones are low, our bodies will attempt to balance out the hormones.
