About this test
A zinc urine test measures how much zinc is being excreted in the urine. It is often used with a blood zinc level to help show whether an abnormal result is caused by dietary intake, poor absorption, or increased loss through the kidneys. Zinc is a trace mineral involved in immune function, wound healing, and growth. Urine testing may be ordered when a provider is investigating persistent deficiency or unusual mineral loss and wants a view of output over time. Results are interpreted alongside blood levels and clinical findings.
What this test measures
- Zinc (urine) Measures the amount of zinc excreted in urine.
- Zinc (serum) Often measured alongside the urine test for comparison.
Who this test may be right for
- People with persistent or unexplained low zinc
- Individuals being evaluated for kidney-related mineral loss
- People with digestive conditions that affect absorption
- Those with symptoms such as poor healing or frequent infections
Before your visit
- A timed or random urine collection may be requested; follow the instructions given.
- Tell the collector about zinc supplements or diuretics you take.
- Follow any instructions provided for your specific panel.
Understanding your results
Urine zinc helps show whether the kidneys are conserving or losing zinc. High urine zinc with low blood zinc may point to increased losses, while low output may suggest inadequate intake or absorption. Results are interpreted with a blood zinc level and your history. Discuss them with a healthcare provider.
