Confused about Low FT3 Level Test Result
I have been reading on the internet and trying to find info on test results, specifically 'normal range' but not in the 'functional range TSH, low T3 and normal T4.  It's tough to find info on the scenario.  I have been hypo for 12 years.  In Feb. my TSH levels were crazy high so my meds were adjusted and in May my TSH levels were slightly low [.23 (Normal range .25-5.0)] but she did not adjust my meds and I am still on the dosage from May of 125mcg.  Now after researching I feel like she should have adjusted them so that I was not being overmedicated.  I don't know if .02 difference would cause hyper symptoms.  I am definitely having symptoms now and very discouraged since I am an avid runner and have not been able to have a good run in over two weeks now.  Any advice would be appreciated. Here are my current levels:  

TSH 0.62 (0.25-5.0)
FT3 3.85 (4.0-8.3)
FT4 15.22 (9.0-20.0)

I have never seen a FT4 lab range like that before.  according to those levels and lab ranges, you are "normal".  i have read enough article about the inaccuracies of thyroid testing that I don't believe any of them are right.      I once had a test that showed low T4 and low TSH---obviously i had something going on besides just a thyroid problem---but the doc was only worried about getting my TSH to a "normal" range---so he lowered my thyroid meds 2 or 3 times, even though It was showing my T4 was too low, he got my TSH normal---but by then my hair was falling out---a different doctor finally saw my last test and said my thyroid was too low!!!  It had been too low all along, but for some reason, the first doctor was only concerned with normalizing my TSH.
