Currently recommended "normal" range for TSH according to AACE is 0.3-3.0. However, many of us had TSH much higher than yours when diagnosed. Mine, for example, was 60-something, and we occasionally see results in the hundreds. So, yes, it can be true.
Were any other tests run?
Do you have hypo symptoms?
Yes. If in doubt, get a copy of your medical lab report :)
