Mark,
The TSH is still too high and the T3 is low normal despite being on Armour Thyroid. She may not be getting enough. I believe this was the women from another post with regards to the OAT and candida?
There are a lot of moving parts in thyroid physiology. There is nothing on the OAT that specifically I saw might contribute to thyroid issues.
She may have some adrenal interference with thyroid function. Adrenal stress and the increase output of cortisol can block T4 to T3 conversion.
I would suggest performing a salivary adrenal profile on her. Also, have her doctor evaluate how much Armour she is taking. It look likes she could use more.
