Hi Val,

I'm not sure I understand what you're saying.

My ft3 was only 283 before I started t3 only. My ft3 on 75 t3 was 357 per Quest

and is now 5.8 on 87.5 t3 per TriCore. But their ranges are MUCH different.

I never take t4 meds because my t4 on NO MEDS is 1.4. I just don't convert.

I am wondering whether I should go back to Quest to compare apples to apples or

just go to TriCore even though their ranges are different.

Thank you,

Kathleen

But did you see the ft3 of 5.8 (
