Apologies, I have edited the post to include my diagnosis and treatment. I'm ordering tests to guide me (not an NHS gp).
BH adrenal saliva is discounted w any purchase over £50 and I'm already ordering a full thyroid panel w rt3. It looks like the BH test is cortisol only whereas the Genova saliva test is cortisol and dhea.
I see that Genova have a urine test that also looks at urinary t3 levels as well as dhea and cortisol. gdx.net/uk/product/adrenal-...
I have Hashi's and am taking 75/100 levo and 100 t3. My symptoms are extreme fatigue and brain fog despite thyroid/nutritional results looking pretty good. My temp is usually low and I have to be quite overmedicated for it to reflect in my pulse/temp. I'm looking to find out if there is an adrenal issue that means that I still feel hypo even though I appear to be on the right dose of meds.
Also in the running are the possibility that the t3 isn't doing its job and/or is being excreted (thus the the rt3 and urine t3 tests). Tbh I'm not even sure how that works and I don't know if I have the means to research it I'm so out of sorts.
Sorry to moan but if I had a penny for every minute I spent lingering slack-jawed over testing options online I could buy us all a round for sure. This is why my self-treatment proceeds at glacial speed.
