Frequently Asked Questions About Pulmonary Function Lab - University Hospital
What is a pulmonary function test?
Pulmonary function tests (PFTs) are noninvasive breathing tests (examples: spirometry, lung volumes/body plethysmography, and diffusion capacity) that measure how well your lungs move air and transfer gases to your blood. They help diagnose and monitor conditions like asthma, COPD and pulmonary fibrosis.
How should I prepare for my pulmonary function test?
Follow your provider's instructions. Common preparation steps include: avoid smoking for several hours before the test, avoid heavy meals, wear loose comfortable clothing, and in many cases avoid using quick‑relief inhalers for about 6–8 hours prior if instructed. Specific medication instructions depend on why the test was ordered—confirm with your provider.
How long will the test appointment take?
A typical pulmonary function testing appointment lasts about 15 to 45 minutes (the actual breathing maneuvers may take only a few minutes; extra time is for coaching, repeat attempts and any exercise testing).
Is the test painful or risky?
PFTs are generally not painful. You may feel lightheaded, dizzy or cough from forced breathing; these effects are short‑lived. Serious complications are rare but some exercise or invasive cardiopulmonary tests have specific risks that the team will review with you.
Should I stop my medications or can I resume normal activities after the test?
Do not stop or change medications unless your provider tells you to. If told to withhold certain inhalers prior to testing, resume them after the test as directed. Most patients can return to normal activities immediately after testing.
When and how will I get my results?
Your healthcare provider or the testing team will review results with you—typically within a few days. If you don't hear back within the timeframe your provider gave you, contact your provider or the testing lab.
