Spirometry is a simple, painless test that measures how much air your lungs can hold and how quickly you can exhale it. It is a key tool in diagnosing asthma, COPD and other respiratory diseases.
When is the test useful?
- Investigating the cause of a lasting cough or breathlessness
- Diagnosing and monitoring asthma and COPD
- Assessing how well treatment is working
Results are interpreted on the spot and the treatment plan refined if needed. The test requires no preparation and takes a few minutes.
