Is spirometry required for the diagnosis of COPD?

• A. Yes, it is essential for diagnosis
• B. No, it is not necessary
• C. Only in advanced cases
• D. Only in patients over 65

Answer: (A)

Spirometry is indeed essential for the diagnosis of Chronic Obstructive Pulmonary Disease (COPD). This pulmonary function test measures the amount of air a person can breathe out and how quickly they can do so. The results help distinguish between COPD and other respiratory conditions, allowing for an accurate diagnosis. Specifically, spirometry assesses the presence of airflow limitation, which is a hallmark of COPD. A key feature of COPD is a post-bronchodilator FEV1/FVC ratio of less than 0.70, indicating persistent airflow obstruction. Reliance solely on clinical history, symptoms, or radiographic findings is insufficient for a definitive diagnosis. Thus, the inclusion of spirometry in the diagnostic criteria is crucial, ensuring that patients receive appropriate treatment and management for their condition.
