Introduction
Asthma is a chronic respiratory condition that affects millions worldwide, and India is no exception. According to the Global Asthma Report 2022, around 1.31 billion people globally suffer from asthma, and India accounts for 6% of this population, with over 30 million people living with the condition. The management of asthma requires regular monitoring, and a Pulmonary Function Test (PFT) is one of the most crucial diagnostic tools to help assess lung function and guide treatment decisions.
For residents of Bangalore, access to a Pulmonary Function Test for Asthma is available at various specialized clinics and hospitals. This article will explore what a PFT entails, why it’s essential for asthma patients, where to get it done in Bangalore, and frequently asked questions related to the test.
What is a Pulmonary Function Test (PFT)?
A Pulmonary Function Test (PFT) is a non-invasive procedure that evaluates the lungs’ ability to move air in and out and how efficiently they transfer oxygen into the bloodstream. It consists of a series of tests that measure different aspects of lung function, including:
- Spirometry: Measures the amount of air a person can exhale after taking a deep breath, along with how quickly the air can be expelled.
- Peak Flow Measurement: Assesses how fast air can be exhaled from the lungs.
- Lung Volume Measurement: Determines the total volume of air in the lungs after maximum inhalation.
- Diffusion Capacity Test: Examines how effectively the lungs can transfer gases (like oxygen) into the bloodstream.
These tests are essential for diagnosing and monitoring asthma, particularly in individuals who experience symptoms like wheezing, breathlessness, chest tightness, and coughing.
Why is a Pulmonary Function Test Essential for Asthma Management?
Asthma is a variable condition, meaning symptoms can fluctuate based on various factors, including environmental triggers, physical activity, and overall health. PFTs provide detailed information about lung function that helps healthcare providers:
- Diagnose Asthma: When symptoms of asthma appear, a PFT can confirm or rule out the condition by evaluating how well the lungs are functioning.
- Monitor Asthma Progression: Regular PFTs can track how asthma changes over time, helping to adjust treatment as needed. For instance, if lung function worsens, it may signal that the current treatment is ineffective or needs modification.
- Assess Response to Treatment: PFTs are used to evaluate whether medications, such as inhalers or bronchodilators, are effectively managing asthma symptoms.
- Detect Airway Obstruction: Asthma often causes airway inflammation and narrowing, which can reduce lung function. A PFT identifies the degree of airway obstruction and helps in planning personalized asthma treatment.

What to Expect During a Pulmonary Function Test
If you’re considering getting a Pulmonary Function Test for Asthma in Bangalore, it’s helpful to know what to expect during the test. The process is typically straightforward and safe:
- Preparation: You may be asked to avoid certain medications or foods before the test. It’s important to follow these instructions for the most accurate results.
- Spirometry: This is the most common component of a PFT. You will be asked to breathe into a mouthpiece connected to a spirometer. After taking a deep breath, you will exhale as forcefully as possible. This measures the volume of air expelled and the speed at which it leaves the lungs.
- Bronchodilator Response Test: In some cases, after the initial spirometry test, you may be given a bronchodilator (an asthma medication). After waiting 15-20 minutes, spirometry is repeated to see if the medication improves lung function.
- Other Tests: Depending on the physician’s assessment, other tests like lung volume measurement or diffusion capacity may be performed to assess the full scope of your lung function.
The entire procedure usually takes around 30 minutes to an hour, and it is painless.
Cost of Pulmonary Function Test for Asthma in Bangalore
The cost of a Pulmonary Function Test for Asthma in Bangalore can vary depending on the diagnostic center or hospital. Typically, the price ranges from ₹800 to ₹2,500. Factors influencing the cost include the type of PFT tests conducted, the healthcare facility, and whether additional tests, such as a bronchodilator response test, are required.
It is advisable to check with the diagnostic center or hospital beforehand to understand the complete breakdown of costs and whether insurance covers the procedure.
Benefits of Regular Pulmonary Function Tests for Asthma Patients
- Early Detection of Worsening Asthma: PFTs can catch early signs of declining lung function, even before symptoms worsen, allowing for timely intervention.
- Customized Treatment Plans: Regular PFTs help healthcare providers tailor asthma treatments, ensuring patients receive the right medications and dosages.
- Prevention of Exacerbations: By monitoring lung function, PFTs can help reduce the frequency of asthma attacks and hospitalizations.
- Improved Quality of Life: By keeping asthma under control, PFTs contribute to better overall well-being, allowing patients to live more active and fulfilling lives.
Frequently Asked Questions
1. How often should I have a Pulmonary Function Test if I have asthma?
It depends on the severity of your asthma and your doctor’s recommendations. Typically, patients with stable asthma are advised to have a PFT once a year. However, if your asthma is more severe or difficult to control, your doctor may recommend more frequent testing.
2. Is the Pulmonary Function Test safe for children with asthma?
Yes, PFTs are safe for children, and they can be especially helpful in diagnosing and managing pediatric asthma. Spirometry is often used to assess lung function in children as young as five years old.
3. Do I need to fast before a Pulmonary Function Test?
No, fasting is not usually required. However, you may be asked to avoid smoking or using an inhaler a few hours before the test. It’s essential to follow the specific instructions provided by your doctor.
4. Can I take my asthma medication before the test?
This depends on the type of PFT being conducted. For some tests, you may be asked to skip your medication to see your lung function without the influence of medication. Always follow your doctor’s advice regarding medication before a PFT.
5. Can I exercise before the test?
It’s generally recommended to avoid strenuous exercise just before a PFT, as it may affect the results. Your doctor will provide guidance on physical activity before the test.
Conclusion
For individuals living with asthma, especially in a bustling city like Bangalore, regular Pulmonary Function Tests for Asthma are crucial in managing the condition and ensuring long-term lung health.
