What are Pulmonary Function tests (PFTS)?

Pulmonary function tests (PFTs) are a group of tests that measure how well your lungs work. This includes how well you’re able to breathe and how effective your lungs are able to bring oxygen to the rest of your body.

How is the PFT different from Spirometry I do at my PCP's office?

While Spirometry only detects air flow, a full PFT includes spirometry,  Lung Volume measurement and Diffusion Capacity. It  gives your doctor much more detailed information as compared to a spirometry alone.

Who should have a pulmonary function test?

Pulmonary function tests are done to diagnose certain types of lung disease, such as asthma, bronchitis and emphysema and to find the cause of shortness of breath. PFTs can be done to measure whether exposure to chemicals at work affects lung function.
