Lung Function Laboratory

What we do

We perform a variety of lung function tests in the lab that provide information to better understand how well your lungs are functioning. Depending on the reason for referral, you may be asked to perform more than one type of test during your appointment.

Who we care for

We accept referrals from doctors (within and external to Alfred Health) for people aged 18 years of age or over who require assessment of their lung function.

What to expect

Prior to commencing the assessments, the Respiratory Scientist performing your assessment will confirm your identity (to ensure we are completing the right assessments for the right person) and check that you are safe to undertake the assessment.

Your weight will be measured at each occasion you attend for assessment. Your height will be measured at your initial visit and the first visit in each calendar year or, if you are under 22 years of age, at each visit. This assists us with calculation of appropriate reference values for interpretation of your results.

We may ask you to provide us with information about medications you take, your smoking history and recent foods you have ingested as these can impact the test results. We will also check that test preparation has been followed for tests requiring test preparation – the instructions will be sent to you with your appointment where test preparation is required.

Most lung function assessments will require you to complete a series of breathing manoeuvres under the direction of a respiratory scientist, generally via a mouthpiece connected to a measurement device. Many of the tests require maximal effort and cooperation from you in order to get valid results. The breathing manoeuvres may make you feel short of breath, puffed or even light headed, but we do allow time between tests for you to catch your breath.

Be sure to let the respiratory scientist know if you are feeling unwell during the tests.

For some tests a blood sample from a finger prick may be required.
