A copper, urine test measures how much copper is leaving your body in urine over a set period, usually 24 hours. It is ordered when a doctor suspects too much or too little copper in the body, or to monitor a known copper-related condition.
What it measures
- Urine copper concentration — The amount of copper in the collected urine sample.
- 24-hour urine copper — Total copper excreted over a full day, which is more reliable than a single sample.
- Creatinine — A substance used to check how well the collection was done and to adjust results.
- Collection volume — Total urine volume, which helps confirm the full 24-hour sample was collected.
Who it is for
Doctors order this test when evaluating suspected copper overload or deficiency, or when monitoring people with known copper metabolism disorders. It may also be used in liver or neurological evaluations.
Preparation
No fasting is usually required. For a 24-hour collection, you will be given a container and instructions to collect all urine for a full day, often discarding the first morning sample and keeping the rest.
Results and what they mean
Results are reported as a concentration or as total copper per 24 hours, along with the collection volume. A clinician interprets the numbers alongside symptoms, diet, medications, and other tests. This is general information, not medical advice; discuss your results with a qualified healthcare professional.

Frequently asked questions
Do I need to fast for this test?
No. Fasting is not typically required for a urine copper test.
Why does the collection last 24 hours?
Copper levels change during the day, so a full-day sample gives a more accurate picture than a single urine sample.
What can affect my results?
Diet, supplements, some medications, and incomplete collection can affect urine copper levels. Tell your clinician about anything you take.
How soon will I get results?
Typical turnaround is 1 to 3 business days after the lab receives your sample.
