Can anyone tell me how reliable is the saliva test for the Adrenal Stress Profile Kit from Genova Diagnostics. I have read somewhere within a previous post that it will only indicate a positive/negative if you are suffering with Addisons. Is it not reliable for Adrenal Fatigue? £97 is a lot of money to part with if it's not a test for Adrenal Fatigue. I received my kit in the post this morning, all ready to carry out tomorrow. I would be grateful for any advice please.
