Spirometry is a breathing test used to measure lung function and help assess respiratory symptoms.
It can support assessment of breathing concerns such as wheeze, breathlessness or possible obstructive lung conditions.
Preparation can vary, so patients should follow the clinic instructions and mention inhalers, recent illness or breathing concerns before the test.
