What is normal range for FreeT4?

Linda1068

I will be having my first blood test for Free T4 on Monday. Does anybody know what the normal range is? Also, the last time I had blood work done, only had result for TSH which was 0.6 . I have been taking Synthroid 25 mcg for the last 2 months and wondering if my TSH will go up or down. I had a PT on 5/1/08 and taking the meds to keep existing thyroid side from overworking. (this is what my Endo said and why he put me on meds).
Thanks.

The range for Free T4 varies from lab to lab.
0.7-1.8 is close, but each lab is a little different.

Where you want to be is about in the middle, or a little higher.

Good luck with your blood tests.
