Pulmonary Function Tests, also called lung function tests or spirometry, are simple and non-invasive tests that measure how well your lungs are working. The tests determine whether or not you have any airflow obstruction or restriction, and whether or not your lung function improves following asthma therapy. Like measuring blood pressure in a person with hypertension, or blood sugars in someone with diabetes, PFTs are essential to diagnose and monitor conditions like asthma and chronic obstructive pulmonary disorder (COPD).

Your allergist will determine if you require spirometry, and your results will be immediately available to review with the team.
