Do your TSH levels stay pretty much the same when taking Levothyroxine? The reason I ask is that mine are different every time and they will only test TSH. I am on 75mg at the moment and my last two tests were
2.9 on 8 January 2015 range 0.35 - 4.5
2.51 on 27 July 2016 range 0.27 - 4.20
Not sure when the range changed but that was on the result print out
