- 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. Find the cause of an underactive thyroid gland (hypothyroidism). 2  TSH levels can help determine whether hypothyroidism is due to a damaged thyroid gland or some other cause (such as a problem with the pituitary gland or the hypothalamus).

Understanding the TSH Test and Its Controversies The TSH test measures the levels of TSH, a hormone that is made and released by your pituitary gland. Your pituitary can sense whether there is enough thyroid hormone in the bloodstream, and it releases TSH when it detects insufficient thyroid hormone. This is why your TSH rises when your thyroid is underactive.

What is TSH? TSH is produced by a small gland in the brain called the pituitary, and can be measured by a common blood test. The hypothalamus, located in the brain, produces thyrotropin-releasing hormone (TRH) that tells the pituitary gland to make thyroid-stimulating hormone (TSH). TSH test is used to check the level of thyroid-stimulating hormone in the blood.

About Hyperthyroidism A TSH or thyroid-stimulating hormone test can be used to reveal a low TSH level in the blood, which is the most accurate indicator of hyperthyroidism. The body shuts off production of this pituitary hormone when the thyroid gland even slightly overproduces thyroid hormone.

- 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. TSH causes the thyroid gland to make two hormones: triiodothyronine (T3) and thyroxine (T4). T3 and T4 help control your body's metabolism. Find the cause of an underactive thyroid gland (hypothyroidism). 2  TSH levels can help determine whether hypothyroidism is due to a damaged thyroid gland or some other cause (such as a problem with the pituitary gland or the hypothalamus).

Thyroid Testing In Dogs TSH STIMULATION TEST. The current “gold standard” test for measuring thyroid gland function is called the TSH stimulation test. In this test, T4 concentrations in the blood are measured before and 6 hours after the administration of TSH (thyroid stimulating hormone or thyrotropin). TSH is the hormone normally produced by the pituitary gland which stimulates the thyroid gland to produce hormone.

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.
