Why This Biomarker Matters

Nail zinc levels may reflect long-term nutritional adequacy. While not standard clinical practice, abnormal levels could suggest zinc deficiency affecting immunity and wound healing.

Overview

This test measures zinc concentration in nail samples to assess long-term zinc nutritional status and exposure. Zinc is essential for immune function, wound healing, protein synthesis, and DNA production. Hair and nail analysis for minerals is promoted in some wellness contexts, though clinical validation is limited. Zinc deficiency can cause slow wound healing, hair loss, and immune problems, while excess zinc can interfere with copper absorption.
