We often hear about LFT (Liver Function Test) for the liver and KFT (Kidney Function Test) for the kidneys. Similarly, there’s a lesser-known but equally important test called the PFT (Pulmonary Function Test), which evaluates lung health. Here’s everything you need to know about it.
What is a PFT Test?
Dr. Bhagwan Mantri, Pulmonology Specialist at Moolchand Medicity Hospital, Delhi, explains that the PFT test measures lung capacity and assesses how well your lungs are functioning. It can help diagnose conditions such as:
-
Asthma
-
COPD (Chronic Obstructive Pulmonary Disease)
-
Pulmonary fibrosis
The test is particularly useful for anyone experiencing:
-
Shortness of breath
-
Wheezing
-
Difficulty breathing during sleep
It evaluates how much air your lungs can inhale and exhale, your breathing rate, and the efficiency of oxygen delivery in your body. Importantly, the PFT test is painless and simple.
Why Should You Get a PFT Test Now?
According to Dr. Mantri, while not everyone needs a PFT, current high pollution levels make it a good time to assess lung health. If you notice persistent coughs, breathing difficulties, or wheezing, getting a PFT can:
-
Detect early signs of lung diseases
-
Help doctors decide if further tests like X-rays or CT scans are needed
-
Prevent serious complications by enabling early treatment
How is the PFT Test Performed?
The PFT test is quick and non-invasive. Here’s what to expect:
-
A small machine is used to measure lung function.
-
You’ll be asked to inhale and exhale normally and then forcefully.
-
The test takes just a few minutes.
-
No fasting or blood sample is required.
Precautions:
-
Avoid smoking before the test
-
Don’t perform the test immediately after heavy exercise, jogging, or climbing stairs
-
Sit comfortably and relax before starting the test
Cost of PFT Test
The PFT test is relatively affordable, with prices ranging from ₹500 to ₹2,000, depending on the hospital or diagnostic center.
Summary:
The PFT test is a simple, painless, and quick way to check lung health, especially when pollution is high or if you experience breathing issues. Early detection can prevent serious lung diseases and help maintain overall respiratory health.
