What is COPD?
COPD is a serious lung disease that over time makes it hard to breathe. You may have heard COPD called other names, like emphysema or chronic bronchitis. COPD stands for Chronic Obstructive Pulmonary Disease.
In people who have COPD, the airways-tubes that carry air in and out of your lungs-are partly blocked, which makes it hard to get air in and out.
This test will help you determine if your symptoms indicate that you might have this disease.
