Is 3.3 in the normal range for a thyroid function test?
If it is the TSH level which is usually what they report when talking tome then yes it’s in the normal range as this is up to 4 or 5 anything above this is bad. As far as I know there aren’t any hormones that should be under 2. I had a thyroid of 3.4 last time and that was in the normal range. The other thing is T4 which is a low number if hypothyroid is a problem.
