first test fasting, second test not? could this make a difference?
I recently was diagnosed by my gynecologist as having hypothyroid. On the first test I was fasting for a blood sugar test and my thyroid results were TSH 5.65, T4 10.2, T3 19 (not sure what kind of test the T3 was said normal range was 24-39?). They put me on 25mcg Synthroid (I have MVP and doctors were worried it would make me jittery to go higher). I just went back last week and the tests come back with TSH 1.5 and T4 9.9 - they didnt do T3 this time because it was an in-house test and they dont do that one. What I want to know is, if possibly because I was fasting the first time, my test results were skewed. It just seems odd to me that such a low dose brought my TSH down so much. I wonder if some how fasting drove my TSH up and I'm not really hypothyroid?
OH .. my apologies .. you are so correct .. they are one in the same. I misread the orig. post as 175mcg's per day ... I guess I got so worried for the member's health on that dosing that I missed you calculated the daily into a weekly dose :)
That leads me to the post above .. if I fast but do NOT take my Synthroid that morning before my bloodwork will that affect my TSH results. I've been on Synthroid for 2.5ysr and at this particular dose for 6 weeks. Thought you may know .. thanks
