Whatever your lab sheet says is the normal range.
It can be different at different labs.

Tha depends on what country you are in and what thyroid test you want the normal range on. AACE lowered he normal range of TSH in 2003 to 0.3 to 3.0. However, most labs still have updated this info and normal will show as 0.3 to 5.5. This leaves many people not getting diagnosed. That's why the word needs to get out to people and to doctors about the new range. Some sources believe that a TSH over 2.0 can cause problems within the body. I know many doctors who treat hypothyroid patients try to get their morning TSH below 2.0 for this reason. I'll include a few links on lab values for thyroid.
I'm on Armour thyroid, so I get my dosage adjusted by the free t4 and free t3 blood tests. I shoot for a midrange or higher free t4 and a high in range free t3. The free t4 and free t3 are the actual amount of hormone that is available for the body to use.
Just in case you were wondering about hyper, I don't believe the range has changed for that. As far as I know its still 0.3. The only way a below 0.3 number is normal is when one is on Armour thyroid or being treated for thyroid cancer.

doctors will tell you anything lower than 3.5 tsh is normal, but actually it should be lower than 2.5. The old range is 5.5
