What it is
A TSH test measures thyroid-stimulating hormone in the blood. It is the most common first test for an underactive or overactive thyroid and is used to monitor thyroid medicine doses.
What the price covers
The price usually covers running the TSH test only. The blood draw and any follow-up thyroid tests, such as free T4, are billed separately.
