Description
A 24-hour urine copper test measures the amount of copper excreted in your urine over a 24-hour period. This test is primarily used to help diagnose Wilson’s disease, a genetic disorder that causes copper buildup in the body. Elevated levels can also indicate other conditions like liver disease.
- High urine copper levels: May indicate Wilson’s disease, other liver disorders, or copper toxicity.
- Low urine copper levels: May suggest conditions like Menkes disease (where the body cannot absorb copper properly) or malnutrition.
- Normal range: Typically, normal urine copper excretion is between 10 and 50 micrograms per 24 hours, according to Mount Sinai. However, normal ranges can vary slightly between laboratories.
