Manganese

This test measures manganese levels in hair samples. Manganese is an essential mineral involved in bone development, metabolism, and nervous system function. Both deficiency and excess are rare in healthy people with adequate nutrition. Hair analysis for manganese is sometimes used to assess nutritional status or environmental exposure, though it is not a standard clinical test. Interpretation is complex and controversial, as hair manganese doesn't always reflect body stores. This test may be ordered for nutritional assessment in specialized situations but should not replace blood testing for clinical diagnosis.
