Normal Controls Needed for Study of Deployment Lung Disease Breathing Test

Trial Objective

The purpose of this study is to learn more about new noninvasive ways of detecting lung disease in US military personnel who were deployed to Iraq and Afghanistan.

We will be conducting a simple breathing test call a lung clearance index (LCI) test. We hope this LCI testing may be useful in detecting early lung abnormalities that may be seen in deployers returning from Iraq and Afghanistan. We are recruiting adults with no history of pre-existing lung disease (for example, asthma, COPD, etc.) and no history of previous deployment to Iraq or Afghanistan to be the normal group that will be compared to participants with known deployment-related lung disease.

Participation involves one 45-60 minute testing session in which you will complete the lung clearance index (LCI) test at National Jewish Health.


This trial is active and currently recruiting.

How to Participate

Who Can Participate

If you are 18 or older with no history of lung disease, you may be eligible to participate. We are matching control subjects with patients who have been diagnosed with deployment-related lung disease, so we will ask about your smoking history, gender, age, race and lung health before scheduling the study visit to be sure you are a match. Smokers are welcome.
