If you take high doses of progesterone, that might.
But the thyroid medication won't mess with those tests as far as I know.
Thanks so much for the reply. I'm glad that sublingual thyroid will not affect the cortisol test. Does that also go for DHEA, Insulin, Gluten, and Progesterone? I forgot to mention that those are going to be included with the cortisol test. It's an Adrenal Stress Index Panel.
Thanks again.
Thyroid hormone, no matter the type, should not interfere with cortisol testing.
Just do nothing by mouth for at least 30 minutes before a saliva test - drinking, brushing teeth etc.
