Unfortunately, testing for mercury needs to be done by a Doctor or other person who knows how to interpret the tests. It's (unfortunately) not as simple as having a hair analysis.

The problem is that in stage 1 and state 2 mercury poisoning, the body absorbs the mercury to keep blood-mercury levels low. Eventually (usually after 10-30 years) the body becomes "saturated" and can no longer store the mercury and it begins to "spill over" into the blood. This is the beginning of stage 3. This usually manifests when people are between 30 and 40 years old, but can vary greatly depending on a variety of factors.

Mercury usually only shows up in the hair when you're entering stage 3, so you can still have toxicity and other mercury-related symptoms but have low hair mercury.

You have to have a variety of tests performed and analyzed to make an accurate call.

This information is from the book It's All In Your Head by Dr. Hal Huggins.

This books get into great detail about the tests you need done and how the Doctor should interpret them. After reading this book, you'll know a lot more than most General Practitioners about performing and interpreting tests for mercury toxicity.

I wish it was simplier but the complexity of it all is part of the reason the "powers that be" have gotten away with this horrible crime for so long (putting mercury?a know super toxin?in so many consumer items).

Hope this helps.
