Bronchodilator Reversibility Test

The Bronchodilator Reversibility Test is a medical procedure used to determine if a person's airway narrowing improves after using a medication called a bronchodilator. During the test, a doctor measures lung function with spirometry, then gives the medication, and repeats the measurements later. If the lung function significantly improves, it suggests the airway obstruction is reversible, which is common in conditions like asthma. This helps doctors diagnose the type of lung problem and decide on the best treatment plan.
