    Hello – the accuracy of the Free T3 (FT3) test versus Total T3 is a subject of some controversy — so there is quite a bit of variability in whether doctors order Free or Total T3. It just depends on the individual doctor’s office.

    No, the guidance doesn’t get into specific dosing scenarios. This is a judgment call that you and your doctor would need to address if T3 remains elevated, while T4 is normal. However, it’s much more common for T3 and T4 to move in the same direction, so hopefully, this won’t be an issue for you.

    Take care!
