Zinc Normal Ranges
Zinc is an essential trace mineral that serves as a structural component of hundreds of enzymes and transcription factors involved in immune function, wound healing, DNA synthesis, cell division, and sensory function (taste and smell).
| Age Group | Reference Range | Unit | Notes |
|---|---|---|---|
| Adults (18–64) | 70 – 120 | µg/dL | — |
Also reported in: µmol/L.
Why Doctors Order the Zinc Test
Zinc deficiency impairs immune function (T cell–mediated immunity), wound healing, and growth in children. It is a significant cause of morbidity in developing countries, contributing to diarrhea, pneumonia, and growth faltering.
How to Enter Your Zn Result
Zinc can be reported in µg/dL or µmol/L. Choose the unit printed next to your result on the lab report so it is compared with the matching reference range.
What a Low or High Zn Can Be Associated With
Below the reference range
- Inadequate dietary intake (common in vegetarians, vegans, elderly)
- Malabsorption (Crohn's disease, celiac disease, short bowel syndrome)
- Alcoholism (increased urinary zinc excretion)
- Acrodermatitis enteropathica (rare genetic zinc malabsorption disorder)
- Burns and major trauma (increased losses)
Above the reference range
- Zinc supplementation (excessive doses)
- Industrial exposure (zinc fume fever)
- Zinc-containing denture creams (chronic copper deficiency from zinc excess is the main risk)
These are common associations, not a diagnosis. A single result is read alongside your symptoms, history and other tests — discuss it with your doctor.
What Can Change Your Zn Result
Before you read too much into a result, consider whether any of these applied:
- Acute phase reaction (zinc is a negative acute phase reactant — infection and inflammation lower serum zinc without true deficiency)
- Meals (postprandial zinc levels fluctuate)
- Hemolysis (zinc intracellular — hemolysis raises serum zinc)
- Contamination from sample collection equipment
Preparing for the test: Draw in the morning fasting. Use trace element–free tubes (royal blue-top, zinc-free).
Symptoms That Often Prompt Zn Testing
- Impaired wound healing
- Recurrent infections (weakened T cell immunity)
- Hyposmia and hypogeusia (reduced sense of smell and taste)
- Hair loss (diffuse alopecia)
- Skin rash (especially around the mouth, hands, and feet)
