Healthy Participants Needed for Lung Disease Study

Trial Objective

Healthy Participants Needed for Lung Disease StudyThe purpose of this study is to learn more about new ways to detect injury or disease in the small airways of the lung.

Spirometry, the most commonly used lung function test, often does not detect disease in small airways. A type of breathing test called the lung clearance index (LCI) has shown promise in detecting small airway diseases in those with conditions such as cystic fibrosis. We will conduct LCI testing in people with chronic lung disease, as well as healthy participants with no history of lung disease, to see if this technique helps to detect abnormalities in small airways. We also will conduct spirometry testing and compare the results to LCI testing to determine if LCI is more effective in detecting abnormal lung function.


This trial is active and currently recruiting.

Who Can Participate

Adults who do not have a history of chronic lung conditions such as asthma and chronic obstructive pulmonary disease (COPD).

Age: 18+    Gender: Any Gender

Estimated Time Commitment

60-90 minute session

Participants will complete a brief questionnaire, as well as spirometry and lung clearance index (LCI) tests.
