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 that can help diagnose various lung conditions, most commonly chronic obstructive pulmonary disease (COPD). Spirometry is also used to monitor the severity of some other lung conditions, and their response to treatment. Note: the information below is a general guide only. Mild COPD-FEV1 is 80% or more of the predicted value. 2  This effectively means that someone with mild COPD can have normal spirometry after bronchodilator medication. 3  Moderate COPD-FEV1 is 50-79% of the predicted value after a bronchodilator. 4  Severe COPD-FEV1 is 30-49% of the predicted value after a bronchodilator.
