| | different range-does it matter?
I got a copy of my thyroid test results and the range for the lab is different than the one I looked at before. This range for the FTI is 6.33-12.40. My value was 9.33, which is just below midrange-the other range I had put me above mid(low end on that range was 4.5). Could midrange just be too low for me, if it is at all near the true free-T4 level? And if so, can a slightly off level cause major symptoms?
