How hair analysis differs from blood analysis, and the value and application of each.
Hair tissue mineral analysis (hTMA), is an analytical test which measures the mineral content of the hair. The sampled hair, obtained by cutting the first inch and one-half of growth closest to the scalp at the nape of the neck, is prepared in a licensed clinical laboratory through a series of chemical and high temperature digestive procedures. Testing is then performed using highly sophisticated detection equipment and methods to achieve the most accurate and precise results.
Hair is an ideal tissue for sampling and testing. It can be sampled easily and painlessly by the patient at home, without the need for a physician. The sample can be sent to the lab without special handling requirements. Clinical results have shown that a properly obtained sample can give an indication of mineral status and toxic metal accumulation following chronic or acute exposure.
hTMA reveals a unique metabolic world: intracellular activity, which cannot be seen through most other tests. This provides a blueprint of the biochemistry occurring during the period of hair growth and development. Examples include:
Trace minerals are essential in countless metabolic functions in all phases of the life process.
Zinc is involved in the production, storage and secretion of insulin and is necessary for growth hormones. Magnesium is required for normal muscular function, especially the heart. A deficiency has been associated with an increased incidence of abnormal heart condi tions, anxiety and nervousness.
Potassium is critical for normal nutrient transport into the cell. A deficiency can result in muscular weakness, mild depression and lethargy. Excess sodium is associated with hypertension, but adequate amounts are required for normal health.
Trace elements (minerals) are more important factors in human nutrition than vitamins. The body can manufacture many vitamins, but it cannot produce necessary trace minerals or get rid of many possible excesses.Dr. Henry Schroeder
There are many factors to take into consideration, for example:
