Bronchodilator Responsiveness Test

The Bronchodilator Responsiveness Test measures how well your lungs respond to a medication that relaxes and opens the airways, improving airflow. During the test, you take a breathing test, usually with a device called a spirometer, to assess your lung function. Then, you inhale a bronchodilator medication, and after a specific time, you repeat the lung function test. Comparing the results helps doctors determine if conditions like asthma or chronic obstructive pulmonary disease (COPD) are present and how well they can be treated with bronchodilators. This test is essential for guiding effective treatment plans.
