Discussions that mention synthroid

Thyroid Disorders board

and was just prescribed Synthroid 2 weeks ago. My dr. only did the TSH. After reading posts on the board, I thought having the other tests might be mroe telling. I'm just not sure what they mean. I can't do Free T3 though. Does anyone have any input on the other tests though or do I need thre Free T3 to get any more detailed info?
