What TSH or thyroid stimulating hormone? A TSH test is done to find out if your thyroid gland is working the way it should. If untreated, a thyroid disorder can cause health problems. TSH stands for “thyroid stimulating hormone” and the test measures how much of this hormone is in your blood. TSH is produced by the pituitary gland in your brain. What is the normal TSH level for thyroid? The normal range of TSH levels is 0.4 to 4.0 milli-international units per liter. If you're already being treated for a thyroid disorder, the normal range is 0.5 to 3.0 milli-international units per liter. A value above the normal range usually indicates that the thyroid is underactive. This indicates hypothyroidism. What does it mean when your TSH level is high? The TSH level in your blood reveals how much T4 your pituitary gland is asking your thyroid gland to make. If your TSH levels are abnormally high, it could mean you have an underactive thyroid, or hypothyroidism. ... If you're making too much thyroid hormone, your TSH will go down.” What does it mean when your TSH is low? Central hypothyroidism. A low TSH level is not always due to suppression caused by high thyroid hormone levels, other conditions, or medications. If thyroid hormone levels are low, a low TSH value can be the result of a central process (hypothalamic or pituitary or both).
