Tissue Mineral
Analysis
Tissue mineral
analysis can
be done on any body tissue, but hair is a non-invasive way to sample. Also, the
reference ranges have been determined mostly for this type of sample. This
technology uses mass spectrometry and it is reliable.
Hair analysis is not diagnostic. Just like any other test in medicine it should be the start of another investigation. In fact a useful way to think of TMA (tissue/hair analysis) is to imagine a map and “home” is the centre of the map. “Home” is the normal range, where we should be. The first TMA is just a map point (GPS position) of where you are at the time. A baseline reading. The test doesn’t tell you how you got there (just like a high blood sugar or cholesterol). The test doesn’t tell you how to get home and it certainly does not depict the terrain of that homeward journey.
In a hair analysis,
most of the nutrient minerals are measured. These are calcium, magnesium,
sodium, potassium, copper, zinc, iron, selenium, chromium, manganese,
molybdenum, phosphorus, cobalt and boron. The test tells whether the
levels are low, normal or high, but more importantly, it tells whether they are in
balance or not. The hair analysis also detects heavy metals such as
lead, mercury and cadmium. In this setting, it is much more sensitive than
a blood test. If you detect lead in the blood, there is already liver
damage. If one can detect cadmium or lead in the blood, there is already
damage done.
The reason for this
discrepancy is that the blood is just a transport system. If all the
minerals were stored in the blood, we would be dead. Most
intracellular mineral stores have the same feature, in that deficiencies don’t
show up in a blood test. Most doctors should know this, but they choose to
believe the blood test rather than the patient.
In terms of the
nutrients, the body tries to keep everything in balance. The common pairs
are calcium-magnesium; sodium-potassium; copper-zinc, copper-molybdenum,
cobalt-potassium and chromium-vanadium as examples. Many illnesses result
from imbalance between these pairs. The commonest abnormalities arise from
imbalances between copper, zinc and molybdenum. This imbalance has at its root
the Estrogen hormones or chemicals which behave as Estrogens (pesticides,
petroleum products, plastics and hormones in food).
Minerals with
charges like sodium, potassium, calcium, magnesium, iron, zinc, copper,
manganese, molybdenum and chromium are very easy to study because deficiencies
of them give “tell-tale” symptoms. There are hundreds of studies in humans
and thousands of studies in animals about the function of these. Therefore
making a list of specific symptoms for each of these could be used in a
questionnaire and correlated to any testing (blood, urine, hair). For hair
analysis, in some situations the symptoms do match the levels, but in many
situations they do not. In the case of magnesium and zinc, normal (and high)
levels can still give rise to symptoms as well as the more obvious low levels.
So is it only low levels that really mean anything or is there a problem
with the interpretation of these too? We sometimes see on hair analysis say,
zero level of potassium or molybdenum. Can we then assume that the level equates
to the whole body? Clearly not, because some of these levels (if extrapolated)
would be incompatible with life! However, the same pattern is probably happening
somewhere in the body and this needs a practitioner to assess. A test is not a
diagnosis.
We believe it is
more fruitful to examine why minerals vary from the reference ranges.
Therefore
evaluation of the nutrient elements should take into account everything that we
know about the patient (including past toxin exposure and the toxic elements).
For instance, Xenoestrogens such as DDT (which cannot be seen on a hair
analysis) typically cause copper levels to rise on hair analysis to over 7 p.p.m.
That is why clinical interpretation will always be more relevant and more
powerful.
At the end of the
day, a test is not a diagnosis; it is just the beginning of another
investigation. In addition, a test is only as useful the person interpreting it.
