Hmmm...interesting. I guess different doctors have different methods. Mine looks at TSH and FT4. I can't remember the last time he checked FT3.

Susan, welcome! My doctor likes to keep my TSH around 1. When it edges up to the top end of the "normal" range (which now is 0.3-3.0, apparently) and above, hypothyroid symptoms kick in. I take both T3 and T4 supplements, and the addition of T3 gave me my life back.

Is your doctor an endocrinologist, or a primary care doctor?
