A TSH test measures the amount of thyroid stimulating hormone (TSH) in your blood. TSH is produced by the pituitary gland and tells the thyroid gland to make and release the hormones thyroxine (T4) and triiodothyronine (T3). See also: T3 test.
Today I would like to look at the TSH (or thyrotropin) reference range. TSH stands for â thyroid-stimulating hormone â. It is secreted by the pituitary gland, and it tells your thyroid to produce thyroxine (T4) and triiodothyronine (T3).or reference range calculations, it is customary to log-transform the TSH results to calculate the 95% reference interval (typical population mean value ~1.5 mIU/L, range 0.4 to 4.0 mIU/L in iodine-sufficient populations).
