THE ACCURACYOF
HAIR MINERAL ANALYSIS
By Lawrence Wilson, MD

Joan,
age 52, wrote us that she sent in a hair sample three months ago. She received her report and her
program, but states that she did not follow the program.
She just sent in a new hair sample
and was dismayed that her new hair test was quite different from the earlier
one, even though she did not follow any healing program.
Now she believes that hair analysis may not be accurate. Let us examine her thought. First, please note the differences on the two tests:

Joan asked why the tests varied, and
questioned the accuracy of the test.
Let us explore several possibilities: 1) laboratory error, 2) incorrect sampling or hair washing procedure
on one or even both samples and 3) changes in body chemistry over the three
months.
Russell
Madarash, laboratory director and chief chemist at Accutrace Laboratories,
supplied the findings of an independent testing organization that checks
results of the testing at his laboratory.
They check both accuracy - the ability to hit the correct number, and precision or reliability - the repeatability of the test.
In
both cases, Analytical Research Labs scored well, in the top 1/3 of about 200
testing laboratories in the nation.
The accuracy and reliability of ARL's hair analysis within two standard
deviations (or 95% of the time) is between plus or minus 3 to 6%.
Some variation occurs and depends on
the mineral tested and on the level of the mineral in the hair. This accuracy is well within acceptable
laboratory standards, and equal or better than most blood or urine tests. Laboratory error is thus an unlikely
possibility.
Errors
in sampling include 1) using long hair, 2) sending in the long ends of the
hair, 3) not sampling close to the scalp, 4) sending dirty, oily or sweaty
hair, or 5) sending hair from different parts of the body without notifying the
laboratory.
Poor sampling procedure is a common
cause of inaccurate results.
Usually, however, they would not vary this much, though anything is
possible if this person used dirty hair, for example. This we cannot control, except to make sure as best we can
that samples look clean and the right length, as this one was.
Some people do not send in the same
hair sample each time, preferring to take hair from different parts of the
head. The type of shampoo or hair
treatments may vary as well. These,
by themselves, will not make much if any difference. As a review, here is the sampling procedure we use.
THE SAMPLING PROCEDURE
For
accurate hair test results:
1) Hair must be cut at or as close
as possible to the scalp, not at the ends of the hair.
Any hair over 1 to 1.5 inches from the scalp must be cut off and thrown
away.
2) Hair must be clean - washed within 12-24 hours before
sampling, preferably in soft water with a non-irritating and basic shampoo.
3) Samples must be from the head,
not pubic hair. With each test use
same area of the body
for an accurate comparison reading.
If possible, use the same area of the head, such as the back or one
side.
VARIATIONS IN BODY CHEMISTRY OVER A THREE-MONTH PERIOD OF TIME
This is the most likely possibility
in this case. I will explain
why. First, I assume that the
patient followed instructions for preparing the hair and cutting the
sample. It is possible, though not
likely, that she did not.
I also assume that the testing
laboratory did not make an error.
They seldom do, and it would not likely be such a variation as we see on
these two tests.
1. Fast Oxidation. Note
first that on both tests, Joan would be classified as a fast oxidizer. I say this because her calcium/potassium ratio is less than
4:1 and her sodium/ magnesium ratio is greater than 4.17:1. This is how we define fast oxidation. See the articles on fast and slow
oxidation on this website for more details about the rationale for these
determinations.
One
of the key characteristics of fast oxidizers is their volatility. This is the reason we always recommend retests for fast
oxidizers within three or four months.
Fast oxidation is difficult to maintain. It is inherently an unstable pattern that can change
quickly.
It is a sympathetic state of body
chemistry. This means that the
sympathetic or fight-or-flight nervous system is dominant at the time of the
testing. This response of the body
is called an alarm reaction in the stress theory of disease as elaborated by
Dr. Hans Selye, MD.
Dr. Selye also called this the
General Adaptation Syndrome or GAS. He wrote
about this in several of his books, such as The Stress Of Life, Calciphylaxis and Stress Without Distress. The books by Dr. Selye are necessary to at least review to
gain a complete understanding and appreciation for the brilliance of the work
of Dr. Paul Eck.
They also help to understand
properly how to interpret a hair mineral analysis. For the reasons above, we see large variations in the
oxidation rate far more often in fast oxidizers than in slow oxidizers.
2. The Christmas season. The first test was cut just before Christmas. For some people, the Christmas season is
highly stressful with family gatherings, parties to attend and more. This could also influence her tissue
mineral patterns, especially as a fast oxidizer.
These individuals are often
high-strung and oversensitive to others.
Calcium and magnesium, in particular, are psychological buffering
elements. Joan is deficient in
both of these in here hair sample and most likely in her bodyÕs tissues.
3. Copper personality type. Note the elevated copper level on her first test. An ideal
copper level in the hair is about 2.5 mg% or 25 parts per million. Joan's copper level of 37 mg% on the
first test is extremely elevated.
This often indicates what we call a
Òcopper personalityÓ. These
individuals are very sensitive to stress and often react with emotion to almost
any situation.
Copper enhances the biogenic amines,
epinephrine, norepinephrine and dopamine.
These are stimulatory neurotransmitters. Copper toxicity is associated with accentuated emotions,
mood swings, anxiety and panic attacks.
Individuals with high copper often go through swings of emotions that
affect the oxidation rate as well as general body chemistry.
4. A Rare Combination. The combination of fast oxidation and elevated copper is
quite rare. This raises another
possibility to explain the variation in the two tests. Most fast oxidizers a have low hair
copper.
Joan
has a combination of the volatility of a high copper level without the
buffering action of adequate tissue calcium and magnesium levels. This makes her body chemistry
especially prone to large fluctuations or variations.
Perhaps
it should be no surprise that Joan listed among her symptoms anxiety,
compulsive behavior, emotional sensitivity, irritability, nervousness, stress
and volatility.
5. Other. This could include other possible events too numerous to list, and could include
any type of stress. It could include a job change, an
illness in herself or a close friend or family member, a death in the family or
any of a hundred others. Once
again, fast oxidizers are even more prone to quick shifts in body chemistry due
to stress of any kind, even a positive change in her life.
Even a change of seasons can rarely
affect the test. The first sample
was cut as winter began, while the second was at the end of the winter season. JoanÕs
oxidation rate slowed dramatically on the second test. If, for example, winter was a stressful
time for Joan, this could account for the variation.
