Breath prints may reveal lung disease secrets without needles
NCT ID NCT04157361
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study is looking for proteins and other markers in exhaled breath that could help doctors monitor lung inflammation and infections in people with asthma or cystic fibrosis. Researchers will collect breath samples from 450 participants (including healthy volunteers) and compare them with standard tests like lung function and imaging. The goal is to develop a simple, non-invasive breath test to track disease activity and guide treatment.
