It took me several years to develope a test that I could trust so I understand you frustration. One of the best self tests is does sugar make you worse and do antifungals make you better. If these are true for you the odds are your complaints are directly related to candida, if not then candida may only be indeirectly involved of at all. Parasitic infections, bacterial dysbiosis, heavey metals and many other candida realted conditions can cause candida like symptoms though candida may not be the primary problem. Look into these other issues if all else fails.
