NCT ID NCT07253883
First seen Jan 10, 2026 · Last updated May 23, 2026 · Updated 17 times
Summary
This study tests a handheld device that measures carbon dioxide in your breath as you breathe normally for 75 seconds. Researchers will use artificial intelligence to see if the device can accurately diagnose asthma or COPD, compared to standard tests that require forceful breathing. The goal is to make diagnosis faster, easier, and more accessible, especially in community clinics. 1,200 adults referred for lung testing will participate.
