0.4 to 4.0 mIU/L
Results. A thyroid-stimulating hormone (TSH) blood test is used to check for thyroid gland problems. The normal values listed here-called a reference range-are just a guide. These ranges vary from lab to lab, and your lab may have a different range for what's normal TSH causes the thyroid gland to make two hormones: triiodothyronine (T3) and thyroxine (T4). T3 and T4 help control your body's metabolism. Triiodothyronine (T3) and thyroxine (T4) are needed for normal growth of the brain, especially during the first 3 years of life. Guide. A thyroid-stimulating hormone (TSH) blood test is used to check for thyroid gland problems. TSH is produced when the hypothalamus releases a substance called thyrotropin-releasing hormone (TRH). TRH then triggers the pituitary gland to release TSH “If you’re making too little thyroid hormone, your TSH will go up. If you’re making too much thyroid hormone, your TSH will go down.”. What’s normal can vary, depending on a number of factors, including the laboratory where your blood test is done, she adds. A normal range for TSH in most laboratories is 0.4 milliunits per liter (mU/L) to 4.0 mU/L. If your TSH is higher than 4.0 mU/L on repeat tests, you probably have hypothyroidism.  The goal of treatment is to get a normal level of thyroid hormone in your body. This is checked using a routine thyroid function blood test called a TSH (thyroid stimulating hormone). A normal range is around 0.4-4.5 mIU/L. This is reached by taking a replacement thyroid ...  Thyroid-stimulating hormone (also known as thyrotropin, TSH, or hTSH for human TSH) is a pituitary hormone that stimulates the thyroid gland to produce thyroxine (T 4), and then triiodothyronine (T 3) which stimulates the metabolism of almost every tissue in the body.  Thyroid-Stimulating Hormone (TSH). Guide. A thyroid-stimulating hormone (TSH) blood test is used to check for thyroid gland problems. TSH is produced when the hypothalamus releases a substance called thyrotropin-releasing hormone (TRH). TRH then triggers the pituitary gland to release TSH If you go by TSH normal ranges your score is normal, however TSH alone does not give a full picture of thyroid health. Insist on testing for Free T4, Free T3, Reverse T3, thyroid antibodies, ferritin and D3 as the first step. One test is just not enough to get a full picture. Hi Diane, I assume the blood test value of 0.03 refers to TSH. Normally the reference range for TSH is around 0.5 to 5.0 but thyroid doctors have been debating these numbers for years. 0.03 is lower than “normal” however TSH does not give Speaking roughly, normal levels of thyroid-stimulating hormone (TSH) are in the range of 0.4 to 4.0 mIU/L. However, each laboratory and test manufacturer identifies its own normal TSH range. This is based on the test, the equipment being used, and the patients being tested. The American Association of Clinical Endocrinologists has proposed a range of 0.3 to 3.0 for normal TSH levels.
