Hair Tissue Mineral Analysis (HTMA)  is a safe and non-invasive test measuring the levels of nutrients and toxic minerals (including heavy metals) found in hair (to parts per million). It  identifies individual nutritional needs and toxic element burdens not revealed in other standard pathology testing. HTMA is one of the most valuable screening tools available in preventative health care, providing accurate, reproducible, clinical results with a gold-standard evidence-based interpretive report.
