Some of the initial tests will be repeated following the medication. This exercise induced asthma test takes approximately 40 minutes to complete and is a safe and effective way to determine if exercise triggers an attack of wheezing, shortness of breath or coughing. A physician's referral is required. The test begins with a pulmonary function test, followed by an exercise test such as running on a treadmill or performing bicycle exercises. A respiratory care practitioner carefully controls the degree of exercise.
Lung function is measured after the exercise test is complete.
Certain medications are not to be taken prior to testing. Your doctor or the respiratory care practitioner will discuss medication restrictions with you prior to your scheduled test. An asthma challenge test takes between 45 to 80 minutes to complete and is useful when there is a strong suspicion of asthma but other asthma related tests show normal lung function. A physician's referral is required. For testing to be accurate, it requires optimum co-operation and effort from the patient.
