From what I have learned through my research there is no reliable test for Candida.
I have had the GI test it came back with a very tiny amount of Candida “nothing out of the normal” the naturopath said.
Oh! Man! was I relieved! I don’t have to do that horrible Candida diet.
Well, FF to a year later and here I am. I don’t think you can depend on these tests. I do think if you suspect that you have Candida then try the diet if you don’t experience die off then you can cross that one off your list.
