L’analyse des cheveux nous donne un compte-rendu des oligo-elements présents et passés.
Différent du sang, les cheveux sont une substance inerte de protéine fibreuse et d’oligo-elements.
Comme les cheveux poussent, venant du sang les éléments nutritifs et toxiques sont déposés dans les follicules pileux et dans les poils. Une fois incorporé, un élément reste fixer dans les cheveux.
C’est très simple de prendre un échantillon de cheveux et l’envoi n’est pas pressé.
L’analyse des cheveux demande une préparation très méticuleuse durant laquelle les contaminations sont éliminées. L’analyse est faite avec les mêmes instruments que le sang et l’urine et demande les mêmes précautions.
Hair analysis, when properly performed, is a reliable measure of tissue levels. Source: Jenkins DW. Toxic Metals in Mammalian Hair and Nails. EPA Report 600, 1979.
For any animal, a silky coat is not just a sign of beauty. The conditon of the animal’s fur is also a
reflecton of its health, just as hair is in humans. Hair or Fur reflects certain health problems.
Fur reflects living conditons
The animal's coat adapts to life in the respectve region it lives in, and thus reflects not only the
climatic but also geological conditons. Grazing animals that eat nutrient-rich grass are better supplied
with nutrients than those that live in barren conditons. If the nutritonal content of the feed is not
balanced, the fur and health of the animal is affected. Some nutrient elements are more needed than
others.
Fur analysis and its advantages
Aside from providing informaton regarding long term or chronic metal exposure, the easy access to
the testng material is an advantage that should not be underestmated. Non-invasive sampling is
problem-free for animals and pet owners.
Needed material: 0.500 grams hair or fur. No mane as these are often treated with metal-containing cosmetics. Sample can be placed with the sample submission sheet in a plain envelope for mailing. Reports are received within one week after sample and submission sheet arrived at our office.
Sample washing before sample submission is not needed, nor do fur or nails be cut with special scissors. The reason is simple: we do wash samples meticulously and repeatedly with deionized solutions. Dust and other contaminants are removed and the sample is then dried in a special drying oven.
Before the spectroanalytical analysis, samples are digested (dissolved) with certified metal-free acids and other solvents in a closed tubes. To fully complete that process, samples are placed in special microwave oven.
With the most modern ICP-MS instrumentation involving cell technique, elemental testing is performed, utilizing certified standards. Unusual results are confirmed through multiple testing.
