Ironically, I just posted on your other thread that healthy people have TSH .3 - 1.0 and that anything over that is suspect for hypothyroidism.
Unfortunately, your lab (just like almost every other one) is using an outdated range. The range was lowered in 2002 to .3 - 3.0 which is really still too high.
While your TSH stands a chance of indicating healthy thyroid function, it certainly wouldn't hurt to confirm thyroid function by looking at the actual levels of thyroid hormone that are available for use by the body:
Free T4 (T4 or thyroxine, free, direct)
Free T3 (tri-iodothyronine, free, serum)
TSH is a pituitary hormone. Looking at that to evaluate thyroid status is like looking at the odometer when you want to know how much gas in in your tank.
For whatever it's worth, my TSH was MUCH lower than yours when I started thyroid hormone replacement.....and my FreeT4 and Free T3 levels were too low for my body's needs.
Do you not have fatigue, anxiety, and/or sleep issues? Any of these can also be caused by hypothyroidism.
In fact, hypothyroidism can manifest in over 300 different ways. You can see just how at the bottom of the following link:hypothyroidmom.com/300-hypothyroidism-symptoms-yes-really/
Just as with Lyme, a person doesn't need to have every symptom on the list to be dealing with the condition. And, Lyme is famous for causing hypothyroidism.
I think it's worth ruling it out.
And, I think it will be worth your while to share your results here. All too many doctors look at in-range levels and declare the patient "normal" when he/she is anything but.
We all know how screening tests fail us as Lymies. Well, the TSH test is really a screening test and sole reliance on it has left over 30 million Americans undiagnosed....and countless improperly treated. Sound familiar?
