Lung Function Test (Pulmonary Function Test) is performed to evaluate how well your lungs work. The test can help to diagnose a lung disease, measure the severity of the lung disease, and check to see how well treatment for a lung disease is working. This test divided into 3 types:

1. Spirometry with or without Bronchodilator
2. DLCO (Diffusion Lung Carbon Dioxide)
3. Body Plethysmography (Lung Volume)


Before the test please DO NOT:

1. Take your nebuliser on the day of the test.
2. Take long acting bronchodilator drug (such as Formoterol, Serevent, Symbicort, Foradale & Spiriva) for 24 hours.
3. Take short acting bronchodilator drug (such as Ventolin, Atrovent, Combivent) for 4 hours.
4. Smoke for 24 hours prior to the test.
5. Consume alcohol for at least 4 hours.
6. Do any vigorous exercise for at least 30 minutes prior to the test.
7. Eat heavy meal at least 2 hours prior to the test.
**Please let us know if you feel unwell before the test.


These procedures are fairly simple and you will need to perform 3 best blowing test. They measure how much air can go inside your lung and how much oxygen goes from your lungs into your blood and lung size.

If you do a simple Spirometry it will take about 10 minutes but a Full Lung Function Test will take approximately 1 hour to complete. These test may be repeated at a later date to measure improvement after treatment.

The result will be sent to the doctor and the doctor will discuss about the result with you at your next appointment.
