Re: low TSH vs low FT3/FT4 question

Sammy64,

I have been trying to find a discussion or information supporting this concept. It does make sense to me for people being treated with T4 only, because they have to push the FT4 up above the mid-point in order to get the FT3 up to just mid-range. But when people are using T4 plus T3, has someone done a survey of some sort to show that the same concept applies? that's what I am wondering about.
thanks for any comments...
