Increased Accuracy After Adjustment of Spirometry Threshold for Diagnosing COPD Based on Pre-Bronchodilator FEV1/FVC.

CONCLUSION: We suggest a slight adjustment using pre-bronchodilator FEV1/FVC < 0.66 when diagnosing COPD based on pre-bronchodilator spirometry. This approach could prevent cases of misdiagnosed COPD, which can lead to potentially harmful treatment of people who do not have COPD and foregone treatment in patients with COPD.
