Blood analysis for minerals is a good indicator of the transport of minerals to and from the storage areas of the body (extracellular).
Hair tissue mineral analysis is a good indicator of the metabolic processes occurring within the cells (intracellular).
Measuring the mineral content of blood gives a good indication of the minerals being transported around the body. However, it can not accurately measure the minerals stored in tissue. Very often, the body’s homeostatic mechanisms maintain proper serum mineral concentrations at the expense of tissue concentrations. Unfortunately, correct serum levels often mask both mineral excesses and deficiencies in tissue mineral concentrations.
■ About 30-40 days after acute lead poisoning, elevated serum lead levels may be undetectable. This is because the body removes lead from the blood as a protective measure and deposits it into tissues such as the liver, bones, teeth and hair.
■ Iron deficiency symptoms are present long before low serum iron levels are detected, because the body depletes stored iron in order to maintain normal serum iron levels. Note: HTMA should be used in conjunction with other appropriate pathology tests for the most comprehensive picture of a person’s health.
■ Only 1 percent of magnesium in the body is distributed in the blood, making a simple sample of magnesium from a serum magnesium blood test not very useful. Most magnesium is stored in the bones and organs, where it is used for many biological functions. Yet, it’s quite possible to be deficient and not know it, which is why magnesium deficiency has been dubbed the “invisible deficiency.
