Lung Function Testing

What is a Lung Function Test?

Lung Function Tests are a group of tests that measure how well your lungs work. This includes how well you’re able to breathe air in and out, and how effective your lungs are able to deliver oxygen to the rest of your body.

Lung Function Tests available
  • Spirometry

  • Gas Transfer

  • Lung Volumes

  • Bronchial Provocation Test

  • Cardiopulmonary Exercise Test

  • 6 Minute Walk Test

  • Maximal Respiratory Pressures (MIPS/MEPS/SNIP).

All tests are conducted by a trained Respiratory Scientist, under the supervision of a Certified Respiratory Function Scientist.

A Lung Function Test is an effective and accurate way to:

  • Help the diagnosis of  lung disease

  • Assist your doctor in being able to offer specific treatment and management of your condition

  • Monitor the lung function of certain conditions

  • Assess pre-operative risk

  • Assess health status prior to employment
