This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
This is a research study that enrolls smokers and people newly diagnosed with chronic obstructive pulmonary disease (COPD)—a progressive lung condition—to thoroughly examine their lungs and overall health. Researchers want to understand which smokers develop COPD, what happens in their bodies, and what other health conditions may be linked to it. The study will help doctors better identify and care for people at risk.
COPD develops in some smokers but not others, and doctors don't fully understand why or how to predict who is at highest risk. This study aims to fill that gap by carefully examining newly diagnosed patients to uncover the patterns and connections that might help prevent or catch the disease earlier.

If you qualify, you will first have a breathing test called spirometry at a doctor's office or hospital to screen for lung disease. If the test shows you may have newly diagnosed COPD, you'll be invited to participate in the full study, where researchers will conduct detailed tests of your lungs and ask about your overall health, including any other medical conditions you may have. The study aims to create a comprehensive picture of your health to help understand how COPD develops.
