Why Test for Zinc?

Zinc is an essential mineral involved in over 300 enzyme reactions, including immune function, wound healing, protein synthesis, and DNA production. Zinc deficiency is surprisingly common, affecting an estimated 17% of the global population—particularly vegetarians, vegans, elderly people, and those with digestive conditions. Testing helps identify deficiency before symptoms become severe and guides appropriate supplementation.

Common Sources of Zinc Exposure

  • Oysters (highest source)
  • Red meat & poultry
  • Shellfish & crab
  • Beans & chickpeas
  • Nuts & seeds
  • Cheese & dairy
  • Whole grains
  • Dark chocolate

Effects of Zinc Exposure

  • Frequent infections
  • Slow wound healing
  • Hair loss
  • Loss of taste or smell
  • Skin problems & rashes
  • Fatigue & lethargy
  • Poor concentration
  • Night blindness

Zinc deficiency symptoms are often non-specific and easily attributed to other causes. Testing is the most reliable way to confirm your zinc status.

Important — Zinc Exposure vs Sensitivity

Blood vs Urine for Zinc: Blood (serum/plasma) zinc is the standard test for assessing zinc status and detecting deficiency. Urine zinc measures excretion and is less commonly used—it may be elevated in certain conditions causing zinc loss. For most people checking their zinc levels, blood is the appropriate test.

Choose Your Sample Type

You can choose between a blood sample or a urine sample using the selector at the top of this page. Both measure zinc exposure but in slightly different ways.

Choose BLOOD if:

  • You want to check your overall zinc status
  • You're vegetarian, vegan, or have limited meat intake
  • You have symptoms of possible zinc deficiency
  • You want to monitor zinc supplementation
  • Your doctor requested zinc testing

Choose URINE if:

  • You're investigating excessive zinc loss
  • You have kidney or liver conditions
  • Your doctor specifically requested urine zinc
  • You prefer home collection without needles
  • Blood testing isn't practical for you

No Fasting Required: You can eat and drink normally before this test. Dietary Note: Zinc can be present in everyday foods. Recent dietary intake may influence urine zinc levels. For the most accurate assessment, maintain your normal diet — your doctor can interpret results in context. For Sensitivity / Allergy Concerns: This test measures systemic zinc levels, not zinc allergy. If you suspect a contact allergy, you'll need a skin patch test from a dermatologist. Sample Collection: Follow the kit instructions carefully. Return your sample using the prepaid envelope on the same day as collection where possible. Avoid posting on a Friday or before a bank holiday.

Zinc is an essential trace mineral involved in immune function, wound healing, protein synthesis, and cell division.
