Everyone at risk for COPD who has cough, sputum production, or shortness of breath, should be tested for the disease. The test for COPD is called spirometry. Spirometry can detect COPD before symptoms become severe. It is a simple, non-invasive breathing test that measures the amount of air a person can blow out of the lungs (volume) and how fast he or she can blow it out (flow).
Spirometry is a test of how well you can breathe and can help in the diagnosis of different lung diseases such as chronic obstructive pulmonary disease (COPD). The test requires taking in a very deep breath and blowing out as fast as possible into a small device called a spirometer.
