About PFT with BDR Test
PFT with Bronchodilator Response (BDR) is an advanced breathing test that also checks if the airways are reacting to the bronchodilator medication during airflow measurements. It measures how much breathing capacity goes up or down before and after breathing the medication, so that it can see whether the narrowing in the airways is reversible.
In Molecular Diagnostics and Therapy, a range of advanced spirometry and pulmonary testing systems offers comprehensive measurement of lung function to aid physicians in the diagnosis and treatment of disorders like asthma and COPD and other obstructive airway diseases.
What is PFT with BDR?
PFT with BDR is an advanced type of spirometry during which lung function is recorded before and after inhalation with a bronchodilator. It assesses lung capacity, the amount of air that can be moved, how much improvement is produced by a drug, and airflow. This examination assists in distinguishing reversible airway diseases, like asthma, from those in which airway obstruction is not so reversible, like COPD.
Common Reasons for PFT with BDR
Evaluation of suspected asthma
Assessment of breathing difficulty
Persistent cough or wheezing
Diagnosis of airway obstruction
Monitoring chronic respiratory diseases
Evaluation of response to inhaler therapy
Pre-operative lung assessment
Follow-up of lung function changes
Conditions Evaluated
Asthma
Helps identify reversible airway narrowing and evaluates improvement after bronchodilator medication.
Chronic Obstructive Pulmonary Disease (COPD)
Assesses airflow limitation and determines the degree of reversibility.
Bronchial Hyperreactivity
Evaluates increased sensitivity of airways causing breathing difficulties and wheezing.
Obstructive Lung Diseases
Helps detect conditions affecting airflow through the lungs.
Treatment Response Assessment
Measures how effectively inhalers or bronchodilator medications improve lung function.
Respiratory Symptoms Evaluation
Supports diagnosis in patients with unexplained cough, breathlessness, or chest tightness.
Who Should Consider This Test?
Your doctor may recommend a PFT with BDR if you:
Experience recurrent wheezing or breathlessness
Have suspected asthma
Have chronic cough
Need evaluation of inhaler effectiveness
Have abnormal spirometry results
Are being monitored for COPD
Require detailed assessment of lung function
Benefits of PFT with BDR
Measures lung function accurately
Determines airway reversibility
Helps differentiate asthma from other lung diseases
Evaluates response to bronchodilator medication
Supports accurate diagnosis and treatment planning
Safe, painless, and non-invasive procedure
Helps monitor respiratory disease progression

Test information: Fasting NOT needed.
Reporting: Within 24 hours*
No fasting is required for the PFT with BDR (Pulmonary Function Test with Bronchodilator Response); however, avoid heavy meals before the examination.
Wear loose, comfortable clothing that allows free movement of the chest and helps you perform breathing exercises easily.
Avoid smoking, vaping, and exposure to respiratory irritants before the test unless advised otherwise by your doctor.
Avoid strenuous exercise or heavy physical activity before the examination to ensure accurate lung function measurements.
Inform your doctor about all inhalers, bronchodilators, respiratory medicines, and other medications you are currently taking, as some medicines may need to be stopped before the test only under medical advice.
Inform your doctor if you have a history of asthma, COPD, lung infection, heart disease, recent respiratory illness, or any other medical condition.
Carry previous PFT reports, Spirometry reports, Chest X-ray, CT Chest reports, respiratory prescriptions, allergy reports, or other medical records, if available, for comparison.
Avoid applying anything that may cause breathing discomfort and wear clothing that does not restrict chest movement.
Follow all instructions provided by the respiratory technician during breathing manoeuvres before and after bronchodilator administration.
Arrive 10–15 minutes before your scheduled appointment for registration and preparation.
PFT with BDR (Pulmonary Function Test with Bronchodilator Response) के लिए आमतौर पर उपवास की आवश्यकता नहीं होती, लेकिन जांच से पहले भारी भोजन करने से बचें।
ऐसे ढीले और आरामदायक कपड़े पहनें जिससे छाती की गतिविधि में कोई रुकावट न हो और आसानी से सांस लेने की प्रक्रिया पूरी की जा सके।
जांच से पहले धूम्रपान, वेपिंग और सांस से संबंधित हानिकारक पदार्थों के संपर्क से बचें।
जांच से पहले भारी व्यायाम या अधिक शारीरिक मेहनत करने से बचें, ताकि फेफड़ों की कार्यक्षमता का सही मूल्यांकन किया जा सके।
यदि आप इनहेलर, ब्रोंकोडायलेटर दवाएं या अन्य सांस संबंधी दवाएं ले रहे हैं, तो इसकी जानकारी डॉक्टर को दें, क्योंकि कुछ दवाओं को डॉक्टर की सलाह के अनुसार जांच से पहले रोकना पड़ सकता है।
यदि आपको अस्थमा, COPD, फेफड़ों का संक्रमण, हाल की सांस संबंधी बीमारी, हृदय रोग या अन्य स्वास्थ्य समस्या है, तो इसकी जानकारी डॉक्टर को अवश्य दें।
यदि उपलब्ध हों, तो पिछली PFT, Spirometry रिपोर्ट, Chest X-ray, CT Chest रिपोर्ट, सांस संबंधी दवाओं की पर्ची या अन्य मेडिकल रिकॉर्ड साथ लेकर आएं।
ऐसे कपड़े पहनें जो सांस लेने में परेशानी न करें और छाती की सामान्य गति को बनाए रखें।
जांच के दौरान श्वसन तकनीशियन द्वारा बताए गए निर्देशों का पालन करें और ब्रोंकोडायलेटर दवा लेने से पहले और बाद में सही तरीके से सांस लेने की प्रक्रिया पूरी करें।
पंजीकरण और जांच प्रक्रिया के लिए निर्धारित समय से 10–15 मिनट पहले पहुंचें।
The patient is seated comfortably, and baseline information regarding respiratory symptoms, medical history, and current medications is recorded.
The patient is connected to a spirometer or advanced pulmonary function testing system to measure baseline lung function.
A nose clip may be placed, and the patient breathes through a mouthpiece connected to the machine.
The patient performs breathing manoeuvres, including deep inhalation followed by forceful and complete exhalation, as instructed by the respiratory technician.
Initial lung function measurements are recorded, including parameters such as forced vital capacity (FVC), forced expiratory volume (FEV1), airflow rate, and other spirometry values.
A prescribed bronchodilator medication is then administered through an inhaler or nebulizer as advised by the doctor.
After allowing sufficient time for the medicine to take effect, the breathing tests are repeated to measure changes in lung function.
The respiratory technician compares the pre-bronchodilator and post-bronchodilator results to assess airway reversibility and response to medication.
The procedure is safe, painless, non-invasive, and generally completed within 45–60 minutes, depending on the patient's response and testing requirements.
The pulmonologist evaluates the results to assess asthma, COPD, bronchial hyperreactivity, obstructive lung diseases, treatment response, and other respiratory conditions.
After detailed analysis, the final report is generally available within 24 hours.
