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."
