thank you very much, it seemed so out of the blue, I think I will as to have t3/t4 tested, I didn't know tsh levels fluctuated so much! and merry christmas to you too
The .6 could have been a fluke or lab error.
It is not unusual for hypers to be hypo first or hypos to be hypo first.
T.S.H. levels fluctuate according to season, health status, diet/nutrition, higher elevation change, ocean, big boulders, time of day and activity level.
Several studies indicate that 20 percent to 30 percent of those with mildly elevated T.S.H. revert to normal within months.
With all these facts taken into consideration, I would do another test in 4 to 6 weeks to see if the .6 repeats or close to it. Also would do FT-4 and FT-3 which go further into the thyroid status.
Good Luck and have a very Merry Christmas!
