sweat/hair tests for mineral deficiencies/toxicities

[Guest guest]

Hi All,

 

Re sweat/hair tests for mineral deficiencies/toxicities: this concept

has been discussed recently on other lists. I was a professional

researcher in mineral imbalances in cattle and sheep for almost 40

years, and summarise as follows:

 

1. IMO, labs that tout hair/sweat analysis as a reliable way to Dx

mineral imbalances are offering an unreliable and discredited

method.

 

2. There is little or no scientific validation for use of hair or sweat to

Dx deficiencies. If you doubt this, check Medline and see how

many papers you can find [relative to papers on blood or liver] to

support the concept!

 

3. BLOOD or reserve tissues (liver biopsy) are the standard tissues

analysed for mineral deficiencies.

 

4. URINE may have some uses in Dx of deficiencies, such as of

Mg or Na. It is especially useful in monitoring heavy metal

excretion following chelation therapy. In that case, the best test is

to compare levels in a sample from a 24-hour (total collection) pre-

chelation versus samples from total 24-hour collections at 1 day

post- and 7 days post- start of chelation.

 

5. HAIR may be of use in toxicities, but hair levels have huge

variations due to differences in the colour of hair [in the same

donor!] and superficial (atmospheric) deposition.

 

6. SWEAT ?? I suspect that [relative to papers on blood] Medline

has very few papers on the usefulness of sweat re mineral status.

 

 

 

Best regards,

Hi Phil,

 

Thanks for the reality check from Western science. It's nice to maintain the integrity of our views of both CM from it's principles and Western science from it's principles.
