Same Day Appointments
Same-day slots are usually available.

Lung function measured properly, to ARTP standards, with a written report the same day. Used to diagnose and monitor asthma and COPD, and required for some occupational health and diving assessments.
Spirometry measures how much air you can move and how quickly, which is the single most useful objective measure of lung function. It is used to diagnose and monitor asthma and COPD, to assess breathlessness, and it is required for certain occupational health and licensing purposes.
The test takes around twenty minutes. You breathe into a mouthpiece and follow the operator’s instructions through several breathing manoeuvres, repeated until consistent readings are obtained. Because the readings are only as good as the technique, the operator coaching you matters as much as the machine. You get your results and a doctor’s interpretation the same day, rather than a set of numbers to take away and worry about.

Same-day slots are usually available.
Clinics are open Monday to Friday 8am to 7pm, and Saturday 9am - 2pm.
Avoid heavy meals, alcohol, and strenuous exercise beforehand, wear loose clothing, and check with us about your inhalers, since bronchodilators may need withholding for a period before the test depending on why you are being tested.

Spirometry measures the volume and speed of air you can breathe out. Two numbers matter most: FVC, the total volume you can force out after a full breath in, and FEV1, how much of that comes out in the first second. The ratio between them tells a clinician whether your airways are obstructed.
That ratio is what separates the two broad patterns. An obstructive pattern, where FEV1 falls disproportionately to FVC, points to narrowed airways as in asthma or COPD. A restrictive pattern, where both fall together, points to the lungs not expanding fully, which has quite different causes. Distinguishing them changes the whole direction of investigation, which is why the interpretation matters as much as the measurement.
Reversibility testing takes this further. The test is repeated after a bronchodilator, and if the obstruction substantially improves, that supports asthma, where the narrowing is reversible. If it does not, that points more toward COPD.
One caveat worth stating plainly: spirometry is effort dependent. If you do not blow as hard or as long as you can, the numbers understate your lung function, which is precisely why the operator coaches you and why the test is repeated until readings are consistent. A poorly performed spirometry is worse than no spirometry, because it produces a number that looks authoritative and is wrong.

It is the main test used in diagnosing asthma, but a diagnosis needs your symptoms and history assessed too. See our asthma page if you have symptoms and want them investigated.
