A lung function test is a series of breathing tests where you will be required to breathe in different patterns through a mouthpiece. These patterns may require you to breath fast, take big breaths in, empty your lungs out and hold your breath. The respiratory scientist conducting the test will talk you through each process. A lung function test is a simple, non-invasive way to examine the lungs and your breathing.
If you take any inhalers bring these along with you to your test. Wear comfortable clothes that will not restrict your breathing
The lung function test generally takes about half an hour. The exact length of the test will vary for each individual.
During the testing you may feel a little bit breathless. The tests can also make you cough and lightheaded for a few seconds. This is normal and you will be given time to recover between tests. There are no side effects from testing and you will be fine to drive home afterwards.
All patients are asked to refrain from the following before all tests:

You have been asked by your doctor to perform a Mannitol Challenge test. During the test you will inhale some Mannitol – which is a sugary powder.
