Blood test may replace pee diaries for bedwetting diagnosis

This study looks at whether a blood test for a substance called copeptin can help doctors diagnose and classify bedwetting in children aged 5-18. Currently, diagnosis relies on a detailed urine diary, which is inconvenient and error-prone. The researchers will compare copeptin levels in 180 children with bedwetting and healthy volunteers to see if it can serve as a simpler, objective tool.
