Pulmonary Function Test (Spirometry) in Guwahati

What is a pulmonary function test (PFT), and why would my doctor order one?

A pulmonary function test (PFT) — most commonly spirometry — is a quick, painless breathing test that measures how much air you can breathe out and how fast. It is the standard first step for diagnosing asthma, COPD, and unexplained breathlessness, and it is often required before surgery to check your lungs are fit for anaesthesia. At Breathe Clinic in Khanapara, our pulmonology team performs spirometry (and, where useful, a FeNO test in the same visit) so we confirm what is actually happening in your airways before starting any inhaler or treatment — not guess.

When you should get a PFT: persistent cough or wheeze, breathlessness on exertion, a smoking history, before planned surgery, or to monitor an already-diagnosed lung condition.

No. You breathe into a mouthpiece following the technician's instructions. It takes about 15-20 minutes and involves no needles or radiation.

Do I need to prepare for a PFT?
Avoid heavy meals and smoking before the test, and your doctor may ask you to pause certain inhalers for a few hours. We will give you exact instructions when you book.
