The T4 test is known as the thyroxine test. The TSH test measures the level of thyroid-stimulating hormone in your blood. These are the two most common thyroid function tests and are usually ordered together. They are routinely performed on newborn babies to identify a low-functioning thyroid gland.
The TSH test, which measures thyroid-stimulating hormone in the blood, is the primary test an endocrinologist gives to diagnose thyroid disease. Endocrinologists also administer T4 and T3 tests, which measure the amount of free, or active, thyroid hormone that is available to body tissues.
