Tsh - 1.39 free t4 - 1.1 free t3 - 2.72 tsh has fluctuated from .99 to 1.19 to 1.51 to 2.77 to .92 to its current 1.39 since last september. free t4 was .72 last year, .92 a few months ago. free t3 was 2.7 a year ago. is this a normal fluctuation?

I would plot these out and show to your local Dr. who will have an idea of how the lab you are using varies over time. I like to figure at least a ± 10% in any lab measurement. If all done in same lab. If not then more variation. Also TSH can vary by time of day. So T4 1.1, .72,.92. So TAKING median of 0.92 =0.092. All are within plus minus 10%. Why are you getting them measured so often?

All laboratory results need to be interpreted in the clinical context and the doctor who ordered the tests is usually in the best position to do that. Talk to the doctor who ordered the tests. Wish you good health!
