Likely normal for ag: These values are likely normal or marginally abnormal for your age. Were you a smoker? Do you have any respiratory symptoms? The criterion for COPD is a persistently reduced FEV-1 below 70%, you need to have this test repeated followed by another measurement after a bronchodilator treatment.
