Zinc: what your result means.

A trace mineral essential for immune function, wound healing, and hormone production. Zinc is measured by blood test as part of the Nutritional panel in the HodieLabs Health Blueprint.

Why Zinc matters

Serum zinc drops during infection and inflammation (redistributed to liver). Interpret away from acute illness. Fasting morning sample is essential. Zinc levels fluctuate with meals and time of day.

Associated risks when out of range: Immune dysfunction (low). Imbalance with copper (contextual).

What the clinical evidence shows

The evidence base behind how the HodieLabs Evidence-Based Clinical Library interprets Zinc, from randomised trials, prospective cohorts and genetic (Mendelian randomisation) studies. Full citations in the reference list below.

• AREDS trial (Archives of Ophthalmology 2001): zinc-containing supplementation slowed progression of age-related macular degeneration in a large randomised trial, one of the clearest demonstrated clinical benefits for zinc in a deficient-risk population.

Evidence-based reference ranges

The HodieLabs Evidence-Based Clinical Library interprets Zinc against published clinical authority standards, never arbitrary "optimal" ranges. Measured in µmol/L:

Clinical interpretation

• Serum zinc drops during infection and inflammation (redistributed to liver). Interpret away from acute illness.
• Fasting morning sample is essential. Zinc levels fluctuate with meals and time of day.
• Zinc competes with copper for absorption. Long-term zinc supplementation can cause copper deficiency.

What improves it: the evidence-based levers

• Dietary optimisation
• Supplementation if low (avoid excess)

Recommended testing frequency: Annual, as part of a comprehensive panel. Single markers are always interpreted in context.

How Zinc testing works at HodieLabs

Zinc is measured in every Health Blueprint at our Melbourne Preventative Health & Longevity Clinic, interpreted by a doctor against the guideline-cited ranges above and tracked over time through your HodieLabs membership.
