The aim of this page is to give you a brief understanding of what to expect when you have lung function test.
There are a number of different tests carried out in the Lung Function department. All of the tests are designed to measure lung capacity, efficiency and airflow through the bronchi (main airways to the lungs).
The results of these tests combined with results from other tests, such as a chest X-ray, medical examination and clinical history, may indicate whether any abnormality is present.
The approximate length of time for your test will be shown on your appointment letter.
