A Pulmonary Function Test (PFT) is a non-invasive diagnostic test used to assess the function of the lungs by measuring lung volumes, airflow, and gas exchange. In Hyderabad, PFTs are commonly advised for people with symptoms such as breathlessness, chronic cough, wheezing, or reduced exercise tolerance. The test plays a key role in diagnosing and monitoring respiratory conditions like asthma, chronic obstructive pulmonary disease (COPD), interstitial lung disease, and occupational lung disorders.
The test is safe, painless, and usually completed within a short time, with results interpreted by experienced pulmonologists. PFTs are also frequently used for pre-operative fitness evaluation, monitoring treatment response, and routine follow-up of chronic lung diseases, helping patients and doctors make informed decisions about respiratory care.
