Can a normal pulmonary function test (spirometry test) rule out copd and emphysema?
2 doctors weighed in across 2 answers
Yes....: In copd, there is chronic obstruction in the airways. In a pulmonary function test, it will reveal this obstruction. If there is no obstruction on the pft, then asthma can still be present but not copd.

Yes: You will have abnormal lung function test if you have COPD or emphysema. Do note that smoking is not good for you at any amount and some genetically-susceptible people may get emphysema even with light tobacco exposure.
