Mine if I recall was very low, so low the doctor said i had no mercury poisoning. Yet I was so toxic with mercury, that I was spitting out saliva daily and anytime I tried to detox from it, i would amost go into convulsions.

SO levels of mercury in blood, urine and hair and not always indicative of what is going on and where it really is. It can cause havoc and be deeply stored, in brain and body tissue and the person can be poisoned up to their eyeballs and have no conclusive test results.
