DirectLabs has a "Thyroid Panel, Special Plus" that has the baseline values needed all in one panel - TSH, FT3, FT4, TPO +TAA. As of this writing it is $159 and a 10% off coupon should be able to be found online with minimal effort. If there is not a LabCorp "patient center" for the blood draw/testing within a reasonable distance from where you live, contact DL directly as they may be able to make alternate arrangements for you if that is the case. See their websites FAQ section for more information concerning.

Other tests that are out there/available are not really necessary in the beginning when determining if you have overt thyroid disease/immune mediated thyroditis that is being missed due to your MD/DO/endo ordering only a TSH or TSH + FT4 if they think they're being really "progressive/aggressive" ( >_< ). Of course, the caveat is "normal" labs still do not rule out subclinical thyroid disease. Reports about "out there" on the interwebz of success working with Naturopaths and the like when that is the case.
