What this test is
This test measures the amount of copper passed in urine, usually collected over a full day. Copper is an essential mineral involved in iron metabolism, nerve function, and connective tissue health. Urine copper can help evaluate whether copper levels in the body are unusually high or low.
What it measures
- Urine copper concentration — reflects the amount of copper present in the urine sample
- 24-hour urine copper — shows total copper excreted over a full day
- Creatinine (if included) — helps verify the completeness of the collection
What the test involves
You will collect all urine produced over a specified period, often 24 hours, into a container provided by the lab. The sample is then sent to the laboratory for analysis.
Why it is often ordered
A clinician may order this test to investigate symptoms or conditions linked to abnormal copper handling, such as unusual fatigue, tremors, or liver concerns. It is also used to monitor known copper-related disorders over time.
Preparation
Preparation steps can vary, so follow the specific instructions provided by the collection lab. This may include avoiding certain foods, supplements, or medications beforehand.
How results are reported
Results are reported as an amount of copper per volume of urine, often with a total for the collection period. Reference ranges differ between laboratories and collection methods, so your report will include the range used by that lab.
