Hi, as far as I know, tests for candida are not overly accurate. Many people with very bad yeast problems (me included) can have tests that show there is nothing much wrong. Similar to mercury. You can show low mercury and still be severely poisoned. Many reasons for this.

I would not bet on any test a doctor gives, I've been there and I wound up not bothering. The best way to test and check for yeast is looking at a symptom profile of candida symptoms and eliminating all sugars/wheat/gluten and high carb foods from your diet and testing reactions. If you have a yeast problem, your symptoms will likely get worse temporarily as the excessive yeast begins to die off (reduce). They literally starve to death because what they need to keep flourishing is being denied.

You will always have a certain amount of yeast in your body and that's normal, but in conditions like ours, the immune system is often unable to keep this yeast in check. The additons of sugars etc just compound the problem and feed this already overgrown yeast and cause it to wreck havoc.

If you go on such a diet, you might need to prepare yourself for the intitial worsening/detox period. But it will be worth it. It can take a few weeks to improve and gain control over yeast (or further control).
