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 official normal range of tsh followed by many doctors and laboratories until 2002 was from between 0 5 to 5 according to this tsh range a tsh over 5 indicated an under active thyroid or hypothyroidism while a low tsh value below0 5 indicated an overactive thyroid or hyperthyroidismo be more specific normal tsh can range from between 0 3 to 5 for instance a person with a tsh range of 4 5 is considered normal by one physician where as another physician can diagnose it as hypothyroidism and begin with the treatment
