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. 1  Spirometry is a very common test to help you and your doctor understand your asthma better, and check how it is improving with treatment. 2  Your doctor may order a bronchodilator to be given as part of spirometry. 3  The doctor may also order tests that measure your lung volumes.
