I doubt it, candida almost ALWAYS has an underlying cause.

Most heavy metal poisoning won't show up on test. Also, you may have a low level but you are sensitive to it which is messing with your immune function.

You may also have a lot of metal hidden in places like the brain where it's hard to pull out and it won't show up in testing. It then may affects a lot of immune and hormonal function of your body.

The key is to see if you respond to chelation. My response is so extreme that it makes me think that heavy metals play a huge role. I have taken thousand of supplements without getting never close to such a response.

As for my case, I know that I don't just have a bad case. I took a whole warehouse of antifungals with going close to nowhere. I feel strongly toxic and after half year on RX tritherapy I came to the evidence that witout clear progresses something else must be at play.
