TSH labs

[gurry]

What is the normal range for TSH labs?  Is it possible to experience symptoms of hyper and hypo thyroid at the same time?  Recently was reduced to 112 of synthroid from 125.  TSH has crept up to 1, whereas usually my TSH hovers around .3-.7.  I seem to feel much better when my TSH is on the right side of the decimal.  My main complaint is that I have experienced breakthrough depression since my dosage was lowered?  How much do those numbers matter where depression is concerned?

TSH is a pituitary hormone and should not be used as the sole number to determine thyroid hormone dosage.  Much more important than TSH is the actual thyroid hormones, Free T4 and Free T3.  Have you had those tested?  If so, what are the most recent results, with reference ranges?  If you haven't had them tested, you should talk to your doctor about getting them tested as soon as possible.  

If your doctor refuses to test them, you should look for a different doctor.

Some symptoms, including depression, can apply to either/both hyper and hypo, so it's impossible to tell just by TSH what you're actually experiencing.

Ranges vary from lab to lab, but ATA and AACE say reference ranges for TSH should be about 0.4 - 4.12.  Ranges for most labs are approximately 0.4 - 4.5 or something similar.
