• A thyroid-stimulating hormone (TSH) blood test is used to detect problems affecting the thyroid gland. TSH causes the thyroid glad to produce two hormones: triiodothyronine (T3) and thyroxine (T4) which help control your body’s metabolism. They’re both needed for normal development of the brain. The tests are run to determine if the thyroid is functioning properly.
