Trace mineral analysis is a test which measures the mineral content of your hair. Mineral content of the hair reflects the mineral content of the body’s tissue. If a mineral deficiency or excess exists in the hair, it usually indicates a mineral deficiency or excess within the body, or an issue with bio-unavailability.
