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.
as we can see from the chart tsh levels normal range is 0 4 4 0 miu l yet people without signs of abnormal thyroid showing tsh result 2 0 miu l and normal t4 test results may acquire thyroid problems later such as hypothyroidismhe function of thyroid stimulating hormone is to activate the thyroid gland for secretion of thyroid hormones pituitary glands command thyroid glands to produce and secrete t3 triiodothyronine and t4 thyroxine hormones associated with thyroid levels it is very important to maintain tsh levels normal range
