Common test: Its a fairly common test used to quantify several different lung functions. Quite useful.

Not very: Pft's are used to evaluate patients with breathing problems that the physician thinks is related to the lungs. If one does not have breathing problems related to the lungs then in general pft's are not indicated.

A 22-year-old female asked:

I had a pulmonary function test. I was curious and wondering can someone be accidentally diagnosed with asthma?

Hard to say: A lot of what is labeled as asthma may not turn out to be over the long run. Most true asthmatics have some related diagnosis in early childhood, males before one and females by three.Yet I have seen a 16 yo female with her first event.Many teens have transient exercised triggered wheezing, which is less worrisome and often fades with age. You can always under-perform on function tests.

What's the question?: As much as we'd like to, nobody here can advise you without our knowing what's troubling you, what your symptoms and signs are, and what you've been told. Pulmonary function tests are of limited value even in arriving at a clinical diagnosis, let alone as a guide to treatment.

Breathing test: The pulmonary function test measures how well air moves in and out of the lungs and what you lung capacity is. Basically you blow into a machine. You may be asked to use an inhaler and the test may be repeated to see if there is any change in the measurements. The pulmonary function test is an important part of an asthma or COPD evaluation and is used to follow your progress to treatment.

PFT...: Pulmonary function tests are tests that measure your respiratory functioning. They will show if you have obstructive or restrictive lung disease as well as give information about the size of your lungs and how gases (oxygen, carbon dioxide) are exchanged. It will also show if the disease present is reversible with medicines, like bronchodilators. They are administered by a respiratory therapist.

Checks lung function: Pfts check numerous areas of lung capacity, flow rates, etc. And are useful in treating/diagnosing emphysema, copd, restrictive ariway diseases, asthma, and understanding lung capabilites prior to surgery. This would be common in smokers, elderly, or in patients with lung diseases like cystic fibrosis. Pfts are easy and done in a lab or pulmonary specialist's facility.
