Clinicians order zinc testing to check for deficiency or excess from supplements. It’s helpful if you have poor diet, gut absorption issues, slow wound healing, taste changes, or frequent infections. It also helps guide safe supplement dosing and whether to check copper. You can test this marker with Aniva across Germany and Finland.

High: Often from supplements, recent lozenges, dehydration, or sample contamination. Long‑term high intake may reduce copper; review your dosing.
Low: May reflect low intake, poor absorption, or shifts during illness and inflammation. Pregnancy and low albumin can lower serum zinc without true deficiency. Include zinc‑rich foods like meat, shellfish, legumes, nuts, and seeds. If results seem off, retest a morning sample when well and after pausing supplements for 24 hours if safe.

• Copper
• Ceruloplasmin
• Ferritin
• Complete blood count
• C-reactive protein
• Albumin

Common factors that can skew results include recent zinc supplements or lozenges, meals, time of day, strenuous exercise, dehydration, acute illness, pregnancy, low albumin, hemolysis, and contamination from non–trace‑metal collection gear. Some medicines (diuretics, penicillamine) and high iron or calcium doses can influence zinc levels or absorption.

Special situations (when to confirm or adjust): test again when recovered from illness, use a morning sample, and review copper if supplementing zinc long‑term.
