What is lung function testing?

Lung function testing also called pulmonary function testing (PFT) is a group of tests that are performed to see how well your lungs work and function. The test measures how much air you take in (inhale), how much air you blow out (exhale), how well your lungs deliver oxygen and the strength of your breathing muscles.

The lung function test can diagnose various lung diseases including asthma, COPD and pulmonary fibrosis. The test may also be used to determine how well treatments and medicines are working to treat lung diseases. Doctors suggest the test when the patient is having symptoms of lung and breathing problems.
