Spirometry tests use a tool called a spirometer to diagnose and track the progression and treatment of certain lung conditions. The spirometer measures how much air you can breathe out in one breath.


1. Why Get a Spirometry Test?

Your doctor will generally do a spirometry test if you're having respiratory problems, either to diagnose or rule out a lung condition. Certain factors raise your risk of a respiratory condition and may make your doctor more likely to run this test; people over 35 who are regular smokers, and those with persistent coughs fall into this category.
