A pulmonary function test is typically performed by a respiratory therapist or other trained pulmonary specialists. There are two types of tests, one uses a spirometer, which is a device with a mouthpiece, and the other uses an air-tight box. If your doctor decides you need a pulmonary function test, you may be sent to a specialist.
Symptoms that may warrant a pulmonary function test include:
Take the following steps to prepare for your pulmonary function test:
Be aware that because the test involves some rapid breathing and forced breathing, you may feel dizzy or lightheaded at times. Let your healthcare provider know if you need to take a break. You may be tired after the test and need some time to rest.
If your results indicate a lung condition, your doctor will talk to you about treatment options, which may include pulmonary rehabilitation, medication, or oxygen therapy. Lifestyle changes can also improve the health of your lungs. Not smoking, eating a healthy diet, exercising regularly, and getting enough quality sleep are all important for lung health. Moreover, staying hydrated can help make the mucus in your lungs thinner and easier to cough up. If possible, avoid dusty or smoky environments.
A pulmonary function test is a test that measures how well the lungs are performing. The test measures several metrics related to lung function, including lung volume, capacity, gas exchange, and rate of flow. The results can help your doctor diagnose and treat certain lung disorders.
Pulmonary function tests can be performed in two ways, depending on the specific information your doctor is looking for. In some cases, your doctor may want to perform both tests, as they measure different things. Your doctor may use a spirometer, which is a device with a mouthpiece, or they may have you stand inside an air-tight box, which looks similar to a telephone booth.
A pulmonary function test measures several components related to lung function. These include:
The cost of a pulmonary function test depends on several factors, such as the type of test you have performed, whether you have one or both tests, where you have your test performed, and whether you have health insurance. Without health insurance, a pulmonary function test can cost from $340 to $830.
If you have health insurance, your pulmonary function test may be covered at 80 to 100 percent of the total. Your insurance company may request a letter from your doctor stating that the test is medically necessary. The amount you are responsible for paying out-of-pocket may depend on whether you have a copay and whether you have met your deductible. If you have questions about what is covered under your specific insurance plan, contact your insurance company.
There are many reasons why someone may get a pulmonary function test. They are sometimes performed as part of a routine physical exam. They may also be required for people working in certain environments that can increase the risk of lung conditions, such as coal mines. Your doctor may also order a pulmonary function test to help diagnose allergies or various lung conditions like asthma, bronchiectasis, emphysema, or chronic bronchitis.
Reading pulmonary function test results requires an understanding of lung function and the normal values for each function measured (total lung capacity, forced vital capacity, residual volume, and functional residual capacity). Your doctor will review your test results with you and let you know of any abnormalities that could be a cause for concern.
The test itself takes about 45 minutes to one hour. The results will need to be read by a pulmonologist, who is a doctor specially trained in lung conditions. The results will then be sent to the doctor who ordered the test for you. You will have a follow-up appointment with your doctor to discuss your results when they are ready.

There are some home lung function tests available. These use a peak flow meter, which you blow into to measure your airflow. These tests are typically recommended for those who have already been diagnosed with a lung condition and need to monitor their airflow regularly. If you have difficulty breathing or other symptoms of a possible lung condition — such as pain when breathing, shortness of breath, or persistent coughing — you should see a doctor for an accurate diagnosis.
