Bronchial Challenge Test on the West Bank
The bronchial challenge test is a common way to determine whether a patient may have asthma. Used more often for adults than children, this test may be performed if your symptoms and screening spirometry do not completely confirm an asthma diagnosis.
During a bronchial challenge test, you will inhale increasing amounts of provocholine mist, which causes the airways to contract involuntarily if you have asthma. If asthma is present, your lung function will drop by at least 20% during this test. Don’t worry – your doctor will administer a bronchodilator at the end of the test to help you regain lung function.
Before partaking in a Bronchial Challenge Test, make sure you tell your doctor if you have recently had a viral infection or any immunizations, as these could affect the test results. You should also avoid smoking and consuming coffee, tea, soda, or chocolate on the day of the test.
