Low TSH; normal T4 FREE

[bearloveravl]

I just received my latest thyroid lab results and my TSH was a 0.06 (range 0.34-5.60) and my T4 FREE is 0.99 (range of 0.61-1.12).  My Dr said to continue my dosage of medications and we would recheck in a year.  Should I be concerned

I am having the same problem. or was. I have had multiple episodes that mimicked thyroid storm. my TSH was .09 and alllll the thyroid specific tests (t4, t3, and the other ones lol) were ALWAYS normal. after my last one at the end of Jan. He put me on a PCU i had it rechecked april 4th and my TSH is lower again!! .07, I begin to develop a nodule that was effecting me swallowing and they ordered an ultrasound. Found out today that I have a 5.2 cm complex cysts on my right lobe (which is the one I knew about) and 2 little  nodules that measure 10mm and 9mm that have microcalcification. I would suggest getting an ultrasound of your thyroid.

Are you having any hyper or hypo symptoms?  Your FT4 is at 75% of range, which is high of the 50% target.  

Does your doctor test FT3?
