PFT Test in Delhi: Procedure, Uses, Benefits & Cost
Pulmonary health plays a crucial role in overall well-being, especially in a city like Delhi, where air pollution levels are often high. Breathing difficulties, chronic cough, wheezing, or unexplained shortness of breath should never be ignored, as they may indicate underlying lung conditions. Doctors often recommend a Pulmonary Function Test (PFT) to evaluate how well the lungs are working. This non-invasive test provides valuable insights into lung capacity, airflow, and gas exchange efficiency. Many patients planning their diagnosis also search for PFT test price in Delhi and PFT test near me to understand both accessibility and affordability before booking the test.
What Is a PFT Test?
A Pulmonary Function Test (PFT) is a group of diagnostic tests that measure how well your lungs are functioning. These tests assess how much air your lungs can hold, how efficiently air moves in and out, and how well oxygen enters the bloodstream. PFTs are widely used to diagnose, monitor, and manage various respiratory conditions.
The test is simple, painless, and usually completed within 30–45 minutes. It is commonly advised for patients with breathing problems, smokers, people exposed to pollutants, and those with a family history of lung disease.
Why Is a PFT Test Important?
The PFT test is important because it helps doctors understand the exact nature of a lung problem. Instead of relying only on symptoms, doctors can get objective measurements of lung performance.
Key benefits include:
Early detection of lung diseases
Monitoring progression of chronic respiratory conditions
Evaluating the effectiveness of ongoing treatment
Assessing lung fitness before surgery
Determining the impact of smoking or environmental exposure
For people living in urban areas, especially Delhi, regular lung assessment can be extremely beneficial due to prolonged exposure to air pollution.
Types of Pulmonary Function Tests
A PFT is not a single test but a combination of different assessments. The most common types include:
Spirometry
This is the most widely performed PFT. It measures how much air you can exhale and how quickly you can do it. It helps diagnose conditions like asthma and COPD.
Lung Volume Test
This test determines the total amount of air your lungs can hold. It is useful in identifying restrictive lung diseases.
Diffusion Capacity Test
This measures how effectively oxygen passes from the lungs into the bloodstream, helping detect conditions that affect lung tissue.
Bronchodilator Test
In this test, lung function is measured before and after inhaling a bronchodilator medicine to assess the reversibility of airway obstruction.
Conditions Diagnosed Using a PFT Test
Doctors recommend PFT tests to diagnose or monitor several respiratory conditions, such as:
Asthma
Chronic Obstructive Pulmonary Disease (COPD)
Chronic bronchitis
Emphysema
Pulmonary fibrosis
Occupational lung diseases
Allergy-related breathing disorders
It is also useful for evaluating unexplained breathlessness and chronic cough.
PFT Test Procedure: Step-by-Step
Understanding the procedure can help reduce anxiety before the test.
You will be asked to sit comfortably and wear a nose clip.
A mouthpiece connected to the spirometry machine will be placed in your mouth.
You will be instructed to take a deep breath and blow out as forcefully as possible.
The test may be repeated several times to ensure accurate readings.
In some cases, you may be given an inhaler and asked to repeat the test.
The entire procedure is safe, non-invasive, and supervised by trained professionals.
How to Prepare for a PFT Test
Preparation is simple but important for accurate results:
Avoid smoking for at least 4–6 hours before the test
Do not consume heavy meals before the test
Wear loose and comfortable clothing
Avoid strenuous exercise on the day of the test
Inform your doctor about any medications you are taking
Your doctor may advise stopping certain inhalers temporarily before the test.
