Blood Test Preparation and Questions

[guavas]

Hi 👋🏻,

I will do DHEA , Aldosterone, BUN, Electrolytes, Creatinine.

I have a question, my lab don’t offer Renin Test.

also what should to do DHEA or DHEA-S

I do that to know if i have adrenal fatigue or not , i will do also Adrenal Saliva Test after do those blood test but i have to do those first.

For now i have already quite caffeine and all my supplement from 1 week, is there is any other thing need to do or is there is any Preparation?

Thanks.
