A member asked:

Should i worry about thyroid. since 2009-2014 tested 3 times for tsh (0.75,1.07,0.98) all normal but low, ref range: 0.35 - 4.00 mciu/ml. just curios to see if numbers are concerning. i feel fine.

Normal: Those TSH values are not just normal, they are pretty ideal. If your TSH was changing dramatically, like if it went up to 3.5 one year, then I'd be concerned. But your numbers are all relatively similar.

Not to worry : The thyroid is a dynamic gland that produces thyroxine hormone whose level fluctuates slightly depending on the time of day as well as other factors. The TSH you have reportedly are not actually "low"; the values are a reflection of a thyroid gland that is operating quite well and quite normally. Not to worry!
