TSH Test. The most common thyroid test is the blood test that measures the amount of thyroid-stimulating hormone (TSH) in your bloodstream. The test is sometimes called the thyrotropin-stimulating hormone test. TSH that is elevated, or above normal, is considered indicative of hypothyroidism.
So your doctor basically uses the TSH to determine whether you're hypo (underactive thyroid) or hyper (overactive thyroid.) If the TSH level is very, very high it means that your thyroid hormone medication has to be increased.
