Pulmonary Function Test (PFT) is a comprehensive assessment used to measure how well your lungs are working by analyzing airflow, lung volume, and gas exchange efficiency. It helps identify respiratory conditions such as asthma, COPD, interstitial lung disease, and other breathing disorders. Performed using advanced equipment, PFT evaluates how much air your lungs can hold, how quickly you can exhale, and how effectively oxygen moves into your blood. The test is non-invasive, safe, and essential for diagnosing lung diseases, monitoring treatment response, and planning personalized respiratory care.
