ANSWER: 03 Apr 2006
Dear Gene,
I've had a look at your website - www.amsalivatesting.com (Update 2012. Site no
longer available) - and the following questions arise, which I hope you can answer.
- I wondered what on earth is meant by a negative test result for heavy
metals - does the saliva test indicate when lead or cadmium etc is MISSING
from the body and needs to be added? The concept of "negative" in relation
to toxics is a nonsense. Could you please explain what is meant on your page
on Reliability (below) and consider replacing the terms "negative" and
"positive" with the terms "low" and "excessive" levels (or similar
meaningful terms) and then define what these are in metric units for each
different heavy metal?
- why wouldn't the collection implements and vessel for saliva samples be
just as prone to tainting as those for collecting urine? What's the
difference in risk of contamination at the sample collection stage?
- what is the "danger level", in metric units, for lead in saliva?
- can you please provide references for the statement in the following
extract on Timing from your pdf which states:
"...several months after continuous [lead] exposure. At this time, lead will
be found... in fatty or lipid tissues, e.g., fat cells..."
In answering question 4., you might also be kind enough to answer the
following query we recently received (for the first time, out of nearly
47,000 queries handled by our information service) - because, perhaps the
question was in response to your website:
"I would just like to ask how are metals, especially lead, able to bind to
fats?"
I look forward to your response at your earliest convenience and thank you
for letting us know about your website.
Yours Sincerely
Elizabeth O'Brien

Reliability
Our saliva test confirms the negative result or positive result of toxic
heavy metals. Saliva tests are 99.9% accurate. They cannot be adulterated or
substituted and the technician administers every collection.
Due to its focus on the chemicals and plasma in the donor's body, saliva
testing is not as susceptible to falsification. Hair products such as
shampoos and bleach can alter hair follicles producing erroneous results,
and urine tests are regularly tainted. As of today, no known methods exist
to alter saliva test results.
[Reference: www.amsalivatesting.com/metals/Saliva_Lead_Testing.pdf]
Timing
Lead found in saliva due to recent exposure will show a danger level much
sooner than the analysis of blood. A danger level in blood may not be
prevalent until several months after continuous exposure. At this time, lead
will be found not only in saliva and blood, but also in bone marrow, in
fatty or lipid tissues, e.g., fat cells, as well as in the nervous system
generally and brain tissue specifically. Once lead has gained access to
these tissue and body areas it is extremely hard, if not impossible to
remove. Most attempts involve painful Chelation with several treatments
using sodium EDTAte or similar substances.
