Nikki,

T4 under 10 would mean you were hypothyroid because your thyroid was not producing sufficient hormone for conversion to T3. If TSH was 1.13 which is low-normal it would indicate secondary hypothyroidism (pituitary dysfunction).

T4 over 24 would indicate hyperthyroid if not on medication or, slight overmedication (up to 28 may be acceptable) if you were on Levothyroxine. TSH would usually be below range or suppressed <0.03.

So if I'm right at the time I was on 150mcg of Levo, it would suggest I was hypothyroid and not over medicated on Levo?

Nikki, you weren't overmedicated with TSH 1.13 and FT4 15. If you were still symptomatic there was room for a dose increase.

So my endo yesterday wanting to take me off Levo, which I already am and stopping t3 would of been the wrong thing to do?

Nikki, I think it's barking. I'd want a second opinion before agreeing to that suggestion.
