I would consider getting other tests. Dr. Mcoomb’s recommends some in his youtube video, if you want to get as close to a real test there is:
He recommends completing 2-3 tests and combine this with your health history, symptoms, including the use of antibiotics to determine whether you have candida overgrowth. You need to figure out what is in the intestinal tract as well as what is in the stool. Genova diagnostic labs has a candida immune complex test and metametrix labs has a GI stool effects test. No western doctor will say that you have it and look at you like you are crazy. A holistic doctor may determine that you have other ailments and specific organs that are damaged and can address these issues seperately.
If you think you have candida; the only way I think you will know whether you have it or not is to do the diet. If you have “die off” symptoms and feel worse once on the diet, this means you have candida in my opinion. I say give the diet a try and very likely you will see improvement.
