Sweat test in babies: comparing arm vs. leg collection
Part of Digestive system, Genetic & congenital, Lungs & breathing clinical trials.
This study compares two ways to collect sweat from babies' arms versus legs to see which works better for diagnosing cystic fibrosis (CF). If your baby is being checked for CF, this trial may help improve the testing process.
Summary written for real people, not researchers, by Clin2.
Who can take part
- Your baby weighs at least 3 kilograms (about 6.6 pounds).
- Your baby is being checked for cystic fibrosis (CF) because of a positive newborn screen, clinical symptoms, or because they have a sibling with CF.
- Your baby does not have serious health problems like heart defects, chromosome issues, or metabolic disorders.
- Your baby does not have eczema or significant skin rashes on their arms or legs.
- Your baby is not taking oral or injected steroids (systemic corticosteroids).
- Your baby is not critically ill (e.g., unstable blood pressure or breathing).
