The peak flow test (peak expiratory flow test or PEF) is a lung function test to measure how fast you can breathe out. You take a full breath in, then blow out as fast as you can into a small, hand-held plastic tube called a peak flow meter.
Your peak flow score – also known as your peak expiratory flow (PEF) – will be displayed on the side of your peak flow meter. This is given in litres of air breathed out per minute (l/min).
What's considered a normal score depends on your age, height and gender.
