Lung function tests are used to help assess and monitor lung disease.
Clinical service overview
There are a number of different lung function tests that measure different aspects of lung function. Depending on the reason for referral and symptoms, more than one test may be undertaken.
Tests available include:
Spirometry – A measure of air movement in and out of the lungs. Assists with identifying ventilatory defects. Can be performed before and after bronchodilator for assessment of reversibility of airflow obstruction.
TLCO – Transfer across the lung of carbon monoxide. This test is an assessment of gas exchange / alveolar membrane integrity.
Lung Volumes (plethysmography) – Measures lung size (eg TLC, FRC, RV). This is useful for detecting restrictive and mixed ventilatory defects.
Maximal respiratory pressures – Provides an indication of global respiratory muscle strength (inspiratory & expiratory).
Bronchial Provocation Test – To assist with diagnosis of asthma or assessment of effectiveness of treatment. The bronchial provocation tests performed at The Alfred are ‘rule in’ tests. That is, a positive finding is indicative of current asthma but a negative finding does not rule out asthma – it may indicate no asthma, mild asthma, or well-controlled asthma.
Cardiopulmonary Exercise Testing (stage 1) – Includes VO2, work, ventilation and heart rate. This is useful for patients with unexplained dyspnoea after other avenues to explain dyspnoea (cardiac / resting respiratory function) have been explored.
Hypoxic Altitude Simulation Test – Assessment of oxygen saturation at simulated altitude (equivalent to maximum cabin altitude of commercial aircraft). This is useful for patients with respiratory impairment who wishing to fly. Note: the outcome of this test should not be used alone to determine fitness to fly.

On the doctor’s behalf, Alfred Health can bulk bill the cost of the consultation for some services through Medicare. This means there is no out of pocket expense to the patient.
MBS-billed services require a current referral. Provide your patient with a 12 month referral to see the specialist of your choice at the requested clinic.
Referrals must be addressed to a named specialist or the Head of service, listed at the top of this page. Clinic consultants are listed on every clinic page.
Note that from time to time, your patient may be seen by another specialist in the clinic, in order to expedite their treatment.
