Copeptin test for excessive thirst and urination in children
Part of Hormones & metabolism, Kidney & urinary, Women’s health & pregnancy clinical trials.
This study tests whether a hormone called copeptin can help doctors tell apart two conditions that cause children to drink and urinate a lot. The results may lead to a simpler, more accurate diagnosis.
Summary written for real people, not researchers, by Clin2.

- You are between 2 and 18 years old.

- Your baseline copeptin level is below 30 pmol/L.
- You agree to take part, and both parents or legal guardians must give their permission.

This study helps doctors figure out why some people drink and urinate excessively. Researchers will measure a hormone called copeptin in your blood after giving you fluids, to find out if your excessive drinking and urination is caused by a specific hormone problem (AVP deficiency) or something else.
This study follows children after brain surgery to see how a substance called copeptin (a marker in the blood) changes and whether it can help doctors spot a condition that causes too much thirst and urination (diabetes insipidus) early. It may lead to better care for children in the ICU.
This study looks at whether a blood test measuring a hormone called copeptin can help diagnose bedwetting in children and tell if it is the only urinary symptom. It aims to make diagnosis easier and more accurate for children who wet the bed at night.
This study tests a new drug called NDI-5001 in adult men with a specific genetic form of nephrogenic diabetes insipidus (a condition where the kidneys cannot concentrate urine properly). The trial checks whether the drug is safe, how your body handles it, and whether it might help reduce excessive urination and thirst.
This study tests whether using two evening dialysis fluid bags (with a special fluid called icodextrin) can help control blood pressure better than the usual one bag. This might be helpful for children who have high blood pressure and low urine output while on peritoneal dialysis.
This trial tests iptacopan (an add-on medicine) in people with idiopathic immune-complex membranoproliferative glomerulonephritis (IC-MPGN), a kidney disease causing significant protein loss in urine. It aims to improve kidney outcomes and safety when added to standard treatments.
