Thyroid-stimulating hormone (TSH)

Also known as: TSH test
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. See pictures of the thyroid gland and the pituitary gland.
