Stool can be used, in some cases, as validation for digestive disorders. It has no direct correlation with the body’s nutritional composition and utilization.
Blood, Serum or Plasma tests measure circulating or “extracellular” levels of cells, enzymes, hormones, minerals, and many organic and inorganic compounds at one moment in time. They do a poor job of estimating “cellular” nutrient uptake, retention and utilization, as they primarily reflect transient nutrient and toxin levels transported by the circulatory system.
Circulating blood nutrient levels can dramatically change between meals. One great example is diabetes with its uncontrolled blood sugar levels. Blood also does not clearly reflect long term heavy metal toxic exposure or provide a precise picture of toxins that are present on the outside of your body. Blood-based toxic metal testing can be expensive and is not as comprehensive or analytical. Most importantly, blood testing does not indicate how the toxic mineral is absorbed and retained by the cells.
Genetic test specimens can be blood, saliva, stool, urine or biopsy-based. They can identify genetic variants or mutations within your DNA such as ancestry, provide genetic risk for some diseases and may indicate “Up or Down Regulation” of a biochemical process. Their traditional diagnostic uses are screening for the presence and proliferation of an infectious agent, identifying genetic markers of specific cancers to direct therapy, recognizing up or down regulation of a biochemical process to assess acute symptoms and epidemiological studies. What they don’t do well is identify the cause of a metabolic disturbance or how to fix it.
Hair is the “most practical method of testing mineral balance”
Hair is the “most practical method of testing mineral balance in your body”1 based on more than 50 years of testing millions of people worldwide. Hair is “the best specimen for the routine screening”1,2 of toxic metals in the body. Finally, hair provides the best long-term information (8 to 12 weeks on average) about the body’s actual retention rates of over 37 minerals, including toxic substances.
