You're welcome.

Like myself, your symptoms are insidious and not showing up on testing. So it leaves you wondering what is wrong and how to fix it. The only thing you can do is address the things that may make a difference, whether it's little or significant. The more you rule out, the better.

Mercury is potent neurotoxin and does not belong in the mouth. So either way, it won't be helping (as you said). So at least you are trying that avenue. Whilst you do this, addressing a possible gluten intolerance and yeast problem will be a really wise move, since so many people with mercury and other toxic/immune conditions can find this a big help. I definitely did. Actually without doing this, I hate to imagine what may have happened. I was so toxic and so ill, I was close to suicide. Had been put on many antidepressants to no avail.

Testing for mercury is very difficult because it is so tightly bound up. Unless a person is acutely poisoned, and/or actively excreting mercury, it may not give a telling level on testing. Usually it require provocation of some kind and that alone can be risky. I had very low levels on hair testing and blood testing and was decided "You don't have mercury toxicity". However, I was indeed highly toxic with mercury, but my body was not excreting it as it should. Low levels can actually be a bad sign in some cases. A doctor here in my country saw my hair test results and was worried because he said "this shows you are not eliminating mercury properly and you are retaining it". They call situations like this "retention toxicity". Those with high levels may either be very poisoned and/or are actively excreting it. So though it shows a mercury toxic condition, it may also show the ability to readily eliminate it.

The more accurate way (apparently) of detecting a hidden mercury problem is by checking the other elements/minerals and there is usually a pattern when mercury is causing problems because it disrupts minerals in the hair.

For me? Mainly the deciding factor was my reactions to amalgam removal, and my response afterwards, plus my symptom exacerbation when trying to detox the stuff. Pretty similar to candida - difficult to test for, but a good way is to experiment with an anti-candida diet. usually if candida is at work, you may experience a "die off" effect, where candida starts to die because it isn't getting the food it requires to thrive on.

It's unfortunate that there are so many ways of getting "false negatives" on testing. Perhaps there are some very clued up health professionals who can understand this more and go further, or at least try things out to see if there is a reaction/response. Basically an exacerbation or improvement. Either is usually a sign you're onto something!
