Breathing problems can sometimes develop gradually without obvious symptoms. A Pulmonary Function Test (PFT) is a non-invasive lung function test that measures how well your lungs move and exchange air. It can help healthcare professionals assess symptoms such as breathlessness, persistent cough, wheezing, or reduced exercise tolerance.
What Does a PFT Check?
PFT evaluates important aspects of lung function, including how much air you can breathe in and out and how effectively you can move air through your lungs. Depending on your symptoms and clinical needs, your doctor may recommend spirometry or other pulmonary function measurements.
Who May Need a PFT?
A lung function test may be recommended for people experiencing ongoing breathing symptoms or for evaluation and monitoring of conditions such as asthma, COPD, or other respiratory disorders. It may also be useful for assessing lung function before certain treatments or procedures.
