Testing is expensive and can be inconclusive. There are some other things that are similar to candida such as H. pylori and parasites, but they are all treated in a similar manner. For long term health, I feel that it all starts in the gut, so if you can get the gut healed…you shouldn’t have too many other problems.
There are 2 labs where you can get your stool tests analyzed and I recommend checking it out if you can afford the tests, they likely won’t be covered by insurance though.
I feel the biggest indication that you have candida overgrowth is if you start our strict diet and antifungals…if you experience die-off symptoms then this likely means you have candida overgrowth. This doesn’t cost any money, lol.
