What it is

A total T4 test measures all the thyroxine hormone in the blood, both bound and free. Most doctors now order free T4 (84439) instead, which is less affected by pregnancy and medicines.

What the price covers

The price usually covers running the test. The blood draw (36415) is often billed as a separate line.
