Pulmonary Function Test (PFT) Services at K J Somaiya Hospital

Accurate lung function assessment to support diagnosis, monitoring, and long-term respiratory care

What Is a PFT Test and What Does It Examine? 

A Pulmonary Function Test (PFT) with spirometry is a simple, safe, and non-invasive breathing test used to assess how well the lungs are functioning. It measures how much air a person can inhale and exhale, and how quickly air can be blown out of the lungs. This helps doctors evaluate airflow limitation and overall respiratory performance. 

At K J Somaiya Hospital, the PFT lung test supports diagnosis and monitoring of respiratory conditions such as asthma, COPD, and chronic bronchitis. It is also commonly advised for symptoms like breathlessness, chronic cough, wheezing, or reduced exercise tolerance. 

A PFT diagnostic test helps assess: 

  • Lung capacity and airflow patterns 
  • Airway narrowing and obstruction 
  • Severity of respiratory disease 
  • Response to inhaler-based treatment 
  • Long-term monitoring of lung function 

During a PFT spirometry test, patients are asked to take a deep breath and blow forcefully into a mouthpiece. The test may be repeated multiple times for accuracy and may also be repeated after inhaler medication as part of a bronchodilator response evaluation. 

PFT Services Offered

The hospital provides comprehensive pulmonary testing to support evaluation and management of respiratory conditions. 

PFT services include: 

  • PFT test for routine respiratory evaluation

FAQs

01. What is a PFT lung test used for?

A PFT lung test is used to evaluate how well the lungs are working by measuring airflow and lung capacity. It helps doctors diagnose and monitor respiratory conditions, especially when symptoms suggest airway narrowing or reduced lung performance. 

A PFT test is commonly advised for: 

  • Breathlessness or reduced exercise tolerance 
  • Chronic cough or wheezing 
  • Monitoring asthma or COPD 
  • Assessing response to respiratory treatment 

Results help doctors plan further evaluation and long-term respiratory care.

02. How does a PFT spirometry test help in asthma diagnosis?

A PFT spirometry test is one of the most common tests used to evaluate asthma. It helps detect airway narrowing and measures how well air flows out of the lungs. 

A PFT test asthma evaluation helps in: 

  • Identifying airflow obstruction 
  • Assessing severity of symptoms 
  • Monitoring response to inhalers or long-term medication 

Doctors interpret spirometry results along with symptoms and clinical history.

03. What is a PFT bronchodilator test (BDR test)?

A PFT bronchodilator test, also known as a PFT BDR test, measures lung function before and after inhaler medication. This helps determine whether airflow improves with bronchodilator treatment. 

This test is useful to: 

  • Assess reversibility of airway obstruction 
  • Support asthma and COPD evaluation 
  • Guide treatment planning and medication response 

It is performed only when clinically advised.

04. What is included in a full PFT test?

A full PFT test may include spirometry along with additional measurements depending on clinical requirement. It is typically advised for patients who need a more detailed lung function assessment beyond basic spirometry. 

A complete PFT test may support evaluation of: 

  • Chronic lung disease severity 
  • Long-term respiratory monitoring 
  • Complex breathlessness symptoms 
  • Treatment response assessment 

The exact test components are decided by the doctor based on symptoms.

05. What is a PFT diffusion test and why is it done?

A PFT diffusion test evaluates how effectively oxygen passes from the lungs into the bloodstream. It helps assess lung gas exchange capacity, especially in certain chronic or progressive lung conditions. 

This test may be advised to: 

  • Investigate unexplained breathlessness 
  • Assess lung damage affecting oxygen transfer 
  • Support monitoring in chronic respiratory disorders 

Doctors interpret diffusion results alongside other PFT findings. 

 

06. Can PFT be used as an allergy-related test?

A PFT is not an allergy test in itself, but it may be recommended when allergy-related symptoms affect breathing. Many patients search for a PFT allergy test when they experience wheezing, coughing, or seasonal breathing difficulty. 

A PFT respiratory test can help: 

  • Identify airway obstruction linked to asthma 
  • Assess breathing difficulty triggered by allergens 
  • Support long-term monitoring of respiratory symptoms 

For allergy confirmation, doctors may advise additional investigations. 

07. Where can I find a PFT test centre near me?

If you are searching for a PFT test centre near you, it is important to choose a facility that follows standardised spirometry protocols and provides accurate interpretation. 

A reliable PFT centre should offer: 

  • Trained supervision during testing 
  • Repeat readings for accuracy 
  • Clear reporting for clinical decision-making 

Hospitals with integrated respiratory diagnostics are usually preferred for dependable results.
