Bronchodilator Reversibility

BDR
Description
"Bronchodilator Reversibility" test evaluates how well your lungs respond to medication that opens the airways. It’s often used to distinguish between asthma and chronic obstructive pulmonary disease (COPD). You’ll perform a spirometry test before and after using a bronchodilator. If lung function improves, it typically suggests asthma. Doctors use the results to refine diagnoses and adjust treatment strategies. Regular monitoring supports better respiratory care and helps track how well your lungs respond to ongoing treatment.

Test Group Description
Complete Pulmonary Function Group: Comprehensive evaluations of respiratory function offer detailed insights into lung function, airway inflammation, and structural abnormalities, facilitating the precise diagnosis and management of pulmonary conditions. Physical Function Group: Tests within this group assess various aspects of physical function, offering insights into an individual's mobility, strength, and endurance. These tests help evaluate overall physical health and identify potential limitations or areas for improvement.
Optimal Range
For All Individuals:
Result: Negative: No abnormalities detected.
Normal Range
For All Individuals:
Result: Negative: No abnormalities detected.
Results That Differ From The Norm (Direct and Indirect Causes)
Abnormal results may indicate:
Asthma (chronic inflammatory airway condition)
Chronic obstructive pulmonary disease (progressive lung disease)
Chronic bronchitis (long-term inflammation of bronchial tubes)
Emphysema (damage to air sacs in the lungs)
Bronchiectasis (abnormal widening of bronchial tubes)
Bronchiolitis (inflammation of small airways)
Allergic bronchopulmonary aspergillosis (fungal lung infection)
Cystic fibrosis (genetic disorder affecting lungs and other organs)
Pulmonary fibrosis (scarring of lung tissue)
Respiratory tract infections (such as bronchitis or pneumonia)
Key Reasons For Testing
Diagnosis of Asthma: Confirms asthma by measuring lung function improvement after bronchodilator use.
Differentiation of Asthma from COPD: Identifies whether airflow issues are due to asthma or COPD based on response to bronchodilators.
Treatment Planning: Guides therapy by assessing how airways respond to bronchodilators or other medications.
Monitoring Disease Progression: Tracks changes in airway function over time to evaluate condition management.

Important Note
Any medical procedure yielding results outside the norm may be directly or indirectly linked to the conditions outlined on this page. Various factors, including genetics, medication and supplement usage, recent illnesses, pregnancy, pre-test eating, smoking, and stress, can impact the test's outcome. Additionally, factors like false positives, false negatives, inaccurate analyses, and others can influence results.
Reference ranges, which help healthcare professionals interpret medical tests, may vary depending on age, gender, and other factors. They may also differ between laboratories due to variations in instruments and methods used. Optimal ranges are designed for preventive purposes, aiming to identify trends and potential risks early, while normal ranges reflect conventional laboratory values indicating no current disease or pathology. Your healthcare practitioner may have specific reasons for testing that deviate from the usual or may interpret results differently based on individual circumstances. Proper interpretation typically involves considering clinical findings and other diagnostic tests. Hence, it is crucial to provide your healthcare professionals with a comprehensive medical history, consult with them for result interpretation, and follow their guidance for potential re-testing or additional diagnostics.
