Can a quick urine test replace the All-Day collection for wilson disease?

This study looks at how copper levels in urine change throughout the day in people with Wilson disease, a genetic condition that causes copper buildup. Currently, patients must collect all urine over 24 hours to monitor treatment, which is inconvenient. Researchers want to see if a shorter 8-hour collection (midnight to 8 am) gives similar results. About 30 patients aged 6 to 70 on standard treatments will participate.
