About Pulmonary Function Test (PFT)
PFT or Pulmonary Function Test is a set of non-invasive breathing tests employed to determine the healthy functioning of the lungs. Measures lung parameters: lung volume, airflow rate, oxygen exchange capacity, and respiratory efficiency. In Molecular Diagnostics and Therapy, high-precision PFT technology allows a comprehensive evaluation of lung function to detect respiratory problems early and follow progression of treatment.
What is a Pulmonary Function Test (PFT)?
The Pulmonary Function Test (PFT) involves the ability of the lungs to accept air inside and outside of the lungs and the efficiency of oxygen transfer in the blood. For the procedure, the patient inhales air using a unique machine known as a spirometer, which measures different parameters of lung activity. The pulmonary tests that can be conducted during the PFT include Spirometry, Lung Volume, and Diffusion Capacity Tests.
Common Reasons for a Pulmonary Function Test
Persistent cough or breathing difficulty
Shortness of breath
Wheezing or chest tightness
Evaluation of asthma
Diagnosis of chronic lung diseases
Pre-operative lung assessment
Monitoring respiratory treatment
Occupational lung disease evaluation
Assessment of unexplained respiratory symptoms
Conditions Evaluated
Asthma
Helps assess airway obstruction and monitor lung function changes in asthma patients.
Chronic Obstructive Pulmonary Disease (COPD)
Evaluates airflow limitation caused by conditions such as chronic bronchitis and emphysema.
Interstitial Lung Diseases
Assesses reduced lung capacity and breathing efficiency caused by lung tissue disorders.
Restrictive Lung Disorders
Helps identify conditions where lung expansion is limited.
Occupational Lung Diseases
Evaluates lung function changes due to workplace exposure to dust, chemicals, or other irritants.
Pre-Surgical Lung Assessment
Determines lung capacity and respiratory fitness before major surgeries.
Who Should Consider This Test?
Your doctor may recommend a Pulmonary Function Test if you:
Experience breathlessness during routine activities
Have a persistent cough or wheezing
Have a history of asthma or COPD
Need evaluation before surgery
Require monitoring of chronic lung disease
Have exposure to respiratory irritants
Need assessment of lung function after treatment

Test information: Fasting NOT needed.
Reporting: Within 24 hours*
No fasting is required for the Pulmonary Function Test (PFT); however, avoid heavy meals before the examination.
Wear loose, comfortable clothing that allows free movement of the chest and abdomen during breathing exercises.
Avoid smoking, vaping, and exposure to respiratory irritants before the test unless otherwise advised by your doctor.
Avoid strenuous physical activity or heavy exercise before the examination to ensure accurate lung function measurements.
Inform your doctor about all respiratory medications, inhalers, or other medicines you are currently using, as some medications may need adjustment before the test.
Inform your doctor if you have a history of asthma, COPD, lung infection, chest surgery, heart disease, or any other respiratory condition.
Carry previous PFT reports, Chest X-ray, CT Chest reports, respiratory prescriptions, laboratory reports, or other medical records, if available, for comparison and accurate evaluation.
Avoid wearing tight clothing that may restrict breathing during the test.
Follow the instructions provided by the respiratory technician and perform breathing manoeuvres as guided for accurate results.
Arrive 10–15 minutes before your scheduled appointment for registration and preparation.
Pulmonary Function Test (PFT) के लिए आमतौर पर उपवास की आवश्यकता नहीं होती, लेकिन जांच से पहले भारी भोजन करने से बचें।
ऐसे ढीले और आरामदायक कपड़े पहनें जिनसे छाती और पेट की गतिविधियों के साथ आसानी से सांस ली जा सके।
जांच से पहले धूम्रपान, वेपिंग और सांस से संबंधित हानिकारक पदार्थों के संपर्क से बचें, जब तक कि डॉक्टर द्वारा अन्य सलाह न दी गई हो।
जांच से पहले भारी व्यायाम या अधिक शारीरिक मेहनत करने से बचें, ताकि फेफड़ों की कार्यक्षमता का सही मूल्यांकन हो सके।
यदि आप इनहेलर, सांस की दवाएं या अन्य नियमित दवाएं ले रहे हैं, तो इसकी जानकारी डॉक्टर या श्वसन तकनीशियन को दें।
यदि आपको अस्थमा, COPD, फेफड़ों का संक्रमण, छाती की सर्जरी, हृदय रोग या कोई अन्य सांस संबंधी समस्या है, तो इसकी जानकारी डॉक्टर को दें।
यदि उपलब्ध हों, तो पिछली PFT रिपोर्ट, Chest X-ray, CT Chest रिपोर्ट, श्वसन संबंधी दवाओं की पर्ची या अन्य मेडिकल रिकॉर्ड साथ लेकर आएं।
ऐसे कपड़े न पहनें जो सांस लेने में परेशानी या छाती की गति को सीमित करें।
जांच के दौरान श्वसन तकनीशियन के निर्देशों का पालन करें और बताए गए तरीके से सांस लेने और छोड़ने की प्रक्रिया पूरी करें।
पंजीकरण और जांच प्रक्रिया के लिए निर्धारित समय से 10–15 मिनट पहले पहुंचें।
The patient is seated comfortably, and basic information regarding respiratory symptoms, medical history, and current medications is recorded before starting the test.
A spirometer or pulmonary function testing device is used to measure different parameters of lung function.
The patient is asked to wear a nose clip and breathe through a mouthpiece connected to the testing machine.
The patient performs different breathing exercises, including deep inhalation followed by forceful and complete exhalation, as instructed by the respiratory technician.
The test measures important lung parameters including lung volume, airflow rate, forced vital capacity (FVC), forced expiratory volume (FEV1), and breathing efficiency.
Additional tests such as lung volume measurement and diffusion capacity assessment may be performed depending on the clinical requirement.
The respiratory technician may repeat the breathing manoeuvres several times to ensure accurate and reliable results.
The procedure is safe, painless, non-invasive, and generally completed within 30–60 minutes, depending on the type of PFT performed.
The pulmonologist evaluates the results to assess asthma, COPD, restrictive lung disorders, interstitial lung diseases, occupational lung diseases, pre-operative lung function, and response to respiratory treatment.
After detailed analysis, the final report is generally available within 24 hours.
