New breath test could replace painful lung scopes
NCT ID NCT04738422
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study aims to see if a simple, non-invasive breathing test can accurately measure the acidity (pH) in the airways, which is often abnormal in lung diseases. Researchers will compare results from this breath test with standard methods in 150 healthy volunteers and people with lung conditions. If successful, this could provide a safer, cheaper way to monitor lung health.
