What it is

A free T4 test measures thyroxine that is not bound to proteins, the active form of the main thyroid hormone. It is usually ordered with or after a TSH test to check for an underactive or overactive thyroid and to adjust thyroid medicine.

What the price covers

The price usually covers the free T4 test only. The blood draw and the TSH test (84443) are billed separately.
