Hello lovely people,
I'm wondering if when you are taking T3 could this lead to higher results for T3 blood tests than those of people who don't have thyroid issues, or who are taking T4 only?
I understand that the more thyroid hormone you take the higher the results will be, so taking more T3 and less T4 will lead to an increase in T3 levels and a decrease in T4 levels. But what I mean is, do the ranges still apply the same way depending on what you are replacing with?
Some more information for those who want it:
I am taking both T3 and T4 and am slowly increasing the T3 while decreasing the T4, with the possible aim of being on T3 only if that's what makes me feel better.
So, I was on 125mcg T4 and 20mcg T3 and my blood test results were:
TSH 0.01 (Range 0.3-5)
FT4 14.3 (Range 9-21)
TT3 2.7 (Range 0.9-2.5)
My endocrinologist was not happy with the 'raised' T3 result and said I was over replacing. I don't have any hyper symptoms and each increase of T3 has made me feel so much better, and I'm personally not particularly concerned at being 0.2 over range, but for now I shall play ball with the Dr's and do what they say as long as I continue to feel better.
Anyway, he reluctantly agreed to let me increase my T3 to 25mcg if I dropped my T4 to 75mcg, which I'm happy to do and feel fine on so far.
Thanks to everyone for reading
