Dear Dr. Hooker,

I see you are a PhD PE too! (chemistry and chemical engineering for
me).

Dr. Walsh refers to the problem that low hair mercury levels do not
exclude intoxication. This is the problem with hair element analysis
- MD's aren't capable of understanding the following boolean truth
table:

Not toxic Yes toxic

Low Hg ? (0) ? (0)

Hi Hg No (0) Yes (1)

This truth table applies to hair, urine and blood mercury levels.

It is possible to tell if someone has mercury poisoning from hair
element analysis if you look at the essential elements, since mercury
impairs mineral transport and they will not be appropriately
distributed (and this impairment of mineral transport sometimes leads
to misleadingly low levels of mercury in hair when it impairs its own
transport). The procedure for doing that is given in the 'counting
rules' Moria mentioned.

About 1/3 of people who are toxic have elevated levels on testing
blood, urine or hair. Most toxic people have deranged hair essential
minerals. Most toxic people also have abnormal results on
fractionated urine porphyrins and some other tests. The use of the
porphyrin test is discussed in another file available on this
listserver's website. The other tests are described in my book
Amalgam Illness: Diagnosis and Treatment, which has a website at
