If my doctor and I suspect exercise-induced asthma, do I need to do a spirometry test or can I just use my peak flow meter?
If your doctor orders an exercise challenge test, you will be asked to do a breathing test before and after you exercise. Your breathing can be checked by performing a spirometry test or blowing into a peak flow meter. While spirometry results provide more information than using a peak flow meter, a diagnosis of exercise-induced asthma can often be made based on the change in peak flow numbers following exercise.
