What is the function of thyrotropin?
Thyrotropin-releasing hormone is the master regulator of thyroid gland growth and function (including the secretion of the thyroid hormones thyroxine and triiodothyronine). These hormones control the body’s metabolic rate, heat generation, neuromuscular function and heart rate, among other things.
What is a normal thyrotropin level?
TSH levels typically fall between 0.4 and 4.0 milliunits per liter (mU/L), according to the American Thyroid Association. Ranges between laboratories will vary with the upper limit generally being between 4 to 5. If your level is higher than this, chances are you have an underactive thyroid.
What does high thyrotropin mean?
High TSH levels can mean your thyroid is not making enough thyroid hormones, a condition called hypothyroidism. Low TSH levels can mean your thyroid is making too much of the hormones, a condition called hyperthyroidism.
What is a critical TSH level?
The standard reference range for the TSH level is anywhere between 0.30 and 5.0 uIU/mL. If your TSH level is higher than 5.0 uIU/mL, then the lab will flag you as “high,” and you may experience the symptoms listed above 5.0 uIU/mL. Values of the TSH level more than 10.0 uIU/mL need long-term thyroid supplements.
What’s a good TSH level?
TSH normal values are 0.5 to 5.0 mIU/L. Pregnancy, a history of thyroid cancer, history of pituitary gland disease, and older age are some situations when TSH is optimally maintained in different range as guided by an endocrinologist. FT4 normal values are 0.7 to 1.9ng/dL.
