Which diagnostic tests are useful for diagnosing hyperthyroidism?

Blood tests that measure thyroxine and thyroid-stimulating hormone (TSH) can confirm the diagnosis. High levels of thyroxine and low or nonexistent amounts of TSH indicate an overactive thyroid. The amount of TSH is important because it’s the hormone that signals your thyroid gland to produce more thyroxine.
