Can I ask what the name of these tests are and how you are going about getting them performed?
I don't think the names will help you at all, because it's a Dutch laboratorium and the names are not linked to the method or anything, just fancy names.
I had to send in some poop samples and they analyzed it. It showed my gut flora like the bacteria. It also showed candida or other yeast/infections. And it showed the secondary line of defence of the immune system (i dont know what its called in english, but google translate says: mucous membrane). Well the results told me that the values of my good bacteria in the gut are pretty low, like bad low. And my ''mucous membrane'' was pretty bad as well. It actually explained a lot, because i'm 4 to 5 times sick during a year.
With the other test i had to submit saliva and urine samples (saliva 8AM 12PM 8PM). And they will test the values of: serotonin, dopamine, (nor)adrenaline, testosteron, cortisol. And i probably forgot one

(i dont have the results from this one yet)
