What is the difference between a blood test and a hair tissue mineral analysis?
I am frequently asked to explain why blood test results for things like blood sugar and thyroid function often differ from those of the Hair Tissue Mineral Analysis (HTMA). It can be quite confusing. Rather than keep on repeating myself, I thought I'd defer to some of the experts who can do a much better job at explaining. The experts at ARL Laboratories in the USA explain the difference between blood tests and HTMA in this newsletter (click the link and enjoy the read):
"In summary, hair analysis and blood analysis are unique and measure different areas of the body. Hair testing is less familiar, but offers a window into the cells to help balance body chemistry."
