A member asked:
My tsh test results 8 months ago were 1.2 but i was tested again last week and the results of tsh - reflex to ft4 are 1.850. is this normal?

Lab variation: Not only may the change in this number reflect a normal variation in the labs result without a change in your thyroid function it could represent normal variation of thyroid function within your own body . This might be as a result of variable absorption of any thyroid supplement you are taking or variation in disease activity if you have a disorder such as hashimoto's thyroiditis.
