Pulmonary health plays a vital role in overall well-being, especially in today’s world, where air pollution, smoking, allergies, and respiratory infections are increasingly common. Doctors often rely on diagnostic tools to evaluate PFT test price how well the lungs are functioning before starting or adjusting treatment. One of the most trusted and widely used investigations for this purpose is the Pulmonary Function Test (PFT). This test helps assess lung capacity, airflow, and oxygen exchange, making it essential for diagnosing and monitoring respiratory conditions. After understanding the basics of lung health and testing methods, many patients also start searching online for PFT test price and PFT test near me to plan their diagnosis conveniently and affordably.
What Is a PFT Test?
A Pulmonary Function Test (PFT) is a group of non-invasive tests that measure how well your lungs are working. These tests evaluate lung volume, capacity, rates of flow, and gas exchange. The results help doctors diagnose lung disorders, determine the severity of respiratory problems, and monitor the effectiveness of ongoing treatment.
PFTs are commonly recommended for people experiencing symptoms such as shortness of breath, chronic cough, wheezing, chest tightness, or reduced exercise tolerance. They are also used before surgeries to assess lung fitness and during routine health check-ups for high-risk individuals.
Types of Pulmonary Function Tests
There is not just one PFT; instead, it includes several tests, each serving a specific purpose:
Spirometry
This is the most common PFT. It measures how much air you can inhale and exhale and how quickly you can exhale. It is crucial for diagnosing asthma and chronic obstructive pulmonary disease (COPD).
Lung Volume Test
This test determines the total amount of air your lungs can hold. It helps identify restrictive lung diseases where lung expansion is limited.
Diffusion Capacity Test (DLCO)
This measures how effectively oxygen passes from your lungs into your bloodstream, often used to evaluate conditions like pulmonary fibrosis.
Bronchodilator Responsiveness Test
It checks lung function before and after inhaling medication to see how well your lungs respond to treatment.
Why Is a PFT Test Important?
The PFT test provides valuable insights into respiratory health. Some key benefits include:
Early detection of lung diseases
Accurate diagnosis of asthma, COPD, and restrictive lung disorders
Monitoring disease progression
Evaluating response to medications
Pre-operative assessment of lung fitness
Because symptoms like breathlessness can be caused by many conditions, PFTs help doctors pinpoint the exact problem and tailor treatment accordingly.
Who Should Get a PFT Test?
A doctor may recommend a PFT test if you:
Have persistent cough, wheezing, or shortness of breath
Are you a smoker or an ex-smoker
Are exposed to occupational dust or chemicals
Have a family history of lung disease
Are diagnosed with asthma, COPD, or interstitial lung disease
Need a lung evaluation before surgery
Athletes and individuals undergoing long-term respiratory therapy may also require periodic PFT testing.
How Is the PFT Test Performed?
The PFT test is usually conducted in a diagnostic center or hospital pulmonary lab. The procedure is simple and safe:
You will be asked to sit comfortably and wear a nose clip.
You breathe into a mouthpiece connected to a machine.
The technician guides you to inhale deeply and exhale forcefully as instructed.
Some tests may require normal breathing, while others need rapid or prolonged exhalation.
The entire process generally takes 30 to 60 minutes. Results are interpreted by a pulmonologist or physician.
Preparation Tips Before a PFT Test
Proper preparation ensures accurate results. Here are some general guidelines:
Avoid smoking at least 4–6 hours before the test
Do not consume heavy meals before testing
Wear loose, comfortable clothing
Avoid strenuous exercise on the test day
Inform your doctor about ongoing medications, especially inhalers
Your doctor may advise stopping certain medications temporarily before the test.
Understanding PFT Test Results
PFT results are presented as numerical values and graphs. These are compared with normal predicted values based on age, height, gender, and ethnicity. Abnormal results may indicate:
Obstructive lung disease (e.g., asthma, COPD)
Restrictive lung disease (e.g., fibrosis, chest wall disorders)
Reduced gas exchange efficiency
Only a qualified doctor can interpret the results correctly and explain what they mean for your health.
PFT Test Price in Delhi
The PFT test price in Delhi can vary depending on several factors, such as the type of test, city, diagnostic center, and whether advanced parameters are included. On average:
Basic spirometry test: ₹1,500 – ₹2,500
Premium hospitals or specialized pulmonary labs may charge slightly higher fees due to advanced equipment and expert interpretation. Always check what parameters are included in the quoted cost.
How to Find a PFT Test Near Me?
Searching for a PFT test near me has become easier with online healthcare platforms. You can:
Use diagnostic center websites
Check hospital lab services
Compare prices and reviews online
Book home sample collection (where available)
When choosing a center, consider accuracy, experienced staff, timely reports, and doctor consultation support.
Are PFT Tests Safe?
Yes, PFT tests are very safe and non-invasive. Some people may feel lightheaded or short of breath briefly during forceful breathing, but this usually resolves quickly. Serious complications are extremely rare.
Conclusion
Pulmonary Function Tests are essential tools for assessing lung health, diagnosing respiratory conditions, and monitoring treatment effectiveness. They are simple, safe, and provide detailed insights into how your lungs work. Whether you are experiencing breathing difficulties or undergoing a routine evaluation, timely testing can make a significant difference in outcomes. Before booking, it is wise to compare the PFT test price and choose a reliable PFT test near me to ensure accurate results, convenience, and value for money.
