Pulmonary function tests or Lung Function tests are noninvasive tests that show how well the lungs are working. These tests measure lung volume, capacity, rates of flow, and gas exchange. This information can help your Doctor diagnose and decide the treatment for certain lung disorders.
Why are these tests done?
Your doctor will order these tests to determine how your lungs are working. If you already have a condition that’s affecting your lungs, your doctor may order this test to see if the condition is progressing or how it’s responding to treatment.
Your doctor may order these tests:
- if you’re having symptoms of lung problems
- if you’re regularly exposed to certain substances in the environment or workplace
- to monitor the course of chronic lung disease, such as asthma or chronic obstructive pulmonary disease (COPD)
- to assess how well your lungs are working before you have surgery
Pulmonary Function Tests can help diagnose:
- asthma
- allergies
- chronic bronchitis
- respiratory infections
- lung fibrosis
- bronchiectasis, a condition in which the airways in the lungs stretch and widen
- COPD, which used to be called emphysema
- asbestosis, caused by exposure to asbestos
- sarcoidosis, an inflammation of your lungs, liver, lymph nodes, eyes, skin, or other tissues
- scleroderma, a disease that affects your connective tissue
- pulmonary tumor
- lung cancer
- weaknesses of the chest wall muscles
