In a 2025 study investigating salivary metabolites as potential biomarkers in cystic fibrosis, researchers identified distinct metabolic patterns linked with key complications as well as correlations with lung function. In this AudioAbstract, Ryan Quigley discusses how a simple saliva sample could provide clinicians with an accessible, non-invasive tool to stratify patients, monitor therapies, and advance personalized care in cystic fibrosis. This topic was also discussed at the 2025 CHEST Annual Meeting.
