While you are at it you may want to do a reverseT3, and total hormones to get a complete picture (total t4 and 3, free t4 and 3, reverse t3, and tsh).
The total is a good indicator of how much your thyroid is making, while the free tells you how much of the hormone is available (not bound to protein) for the body to use. If reverset3 is high it will outcompete t3 in the body.
