RE: Results after 6 weeks of T4 treatment, low RT3, high TSH.

[Guest guest]

Hi fragrance,

RT3 should be low- this is an inert product of conversion of T4 to T3 that sometimes goes haywire with the T4 converting to RT3 instread of T3.

It's when your rT3 is high that you should worry Fragrance. Being low is fine, so you can cross that off your list of concerns. Your FT4 and FT3 look fine. Your iPTH is at the top of the range, and hopefully, somebody else will be able to help as to what this really means.
