NCT ID NCT07253883
First seen Jan 10, 2026 · Last updated May 08, 2026 · Updated 12 times
Summary
This study tests a handheld device that measures carbon dioxide in your breath to diagnose asthma or COPD. Instead of forceful blowing tests, you just breathe normally for 75 seconds. The results will be compared to standard diagnosis in 1,200 adults referred for lung testing. If accurate, this could make diagnosis faster and easier, especially in community clinics.
