My last thyroid test was much higher than what it has averaged the last 10 years. But was still within “normal” limits. My previous endo was aggressive with keeping at lower end of range. But current one doesn’t agree. (I have been on T-meds synthroid, levoxyl, etc for over 30 years).
So i agreed to wait and get another test, which is coming up. I did have, and still have symptoms related to low thyroid, but until i saw previous results, had attributed that to other factors.
Any suggestions regarding thyroid ranges that work for you ? (TSH)
For example i found this, supporting lower ranges.
What should your TSH level be?
Normal TSH levels for the average adult range from 0.4 ‑ 4.0 mIU/L (milli-international units per liter) (3).
However, many organizations agree that a reading of 2.5 or less is truly ideal for normal thyroid levels, with anything 2.5 – 4.0 mIU/L considered “at risk”.
