What can — and can't — hair mineral analysis tell a dietitian or functional medicine practitioner? A look at the evidence, the interpretive limits, and where HTMA fits into a broader clinical workflow.
Evidence-based review of the most common misconceptions about Hair Tissue Mineral Analysis (HTMA): diagnosis, laboratory comparability, mineral-ratio typing, toxicity, hair vs blood levels and single-test limitations.
How reference ranges are built for Hair Tissue Mineral Analysis (HTMA), how population-derived reference intervals differ from functional or optimal ranges, and why the distinction changes how a result should be read.
