The 24-Hour Urine Copper Test measures the amount of copper excreted in urine over a full day to assess liver and metabolic health. Copper is an essential mineral required for energy production, red blood cell formation, and nerve function. Abnormal copper levels can indicate conditions like Wilson’s disease, liver disorders, or copper metabolism imbalance. This test helps doctors diagnose and monitor such conditions, ensuring timely treatment and maintaining healthy copper balance in the body.
