Have you done a candida questionare, that is how many drs come to a diganosis and you can find them all over the internet.
Stool tests are a waste of time in my opinion as are urine test sthat test for D-arbintol( a waste product of candida). I found my most accurate results in a blood test for Candida Immune Complexes. Not tests are 100%. Not everyone has immune complexes in their blood to detect...does not mean you do not have candida.
Try the diet and antifungal like garlic, if you feel worse, you have candida.
