Pulmonary Lung Function Test in Crystal Lake IL Area

A pulmonary lung function test is a diagnostic test that measures how well your lungs are functioning. The results of this diagnostic test can help your doctor determine if you have a lung disorder or if your lungs are healthy. It can also assist an allergist in helping a patient with a respiratory reaction to certain allergens. Dr. Noga Askenazi and her associates at Advanced Allergy & Asthma Associates S.C., Inc. encourage patients to ask about ways to check lung capacity using the pulmonary lung function test.

What Type of Testing Can Be Performed, and What Can I Expect?

There are two types of pulmonary lung function tests: spirometry and diffusion capacity.

Spirometry is the most common type of test and measures how much air you can inhale and exhale in one breath.
Diffusion capacity measures how well oxygen passes from your lungs into your blood.

Both tests are painless and only take a few minutes to complete. During this test, you will be asked to breathe into a mouthpiece connected to a machine called a spirometer or diffusing capacity machine.

What Happens After I Receive the Results of My Pulmonary Lung Function Test?

The test results will be compared to a reference value that considers your age, gender, height, and weight. A lung function test is considered abnormal if your results are below the reference value. It does not necessarily mean you have a lung disorder if you have abnormal results. Many factors, such as smoking, can affect your lung function. Dr. Noga Askenazi will interpret your results and order additional testing if needed.
