Diagnosing Asthma and Asthma Tests

After talking with you about your asthma symptoms and possible asthma triggers, your doctor will do a physical exam, laboratory testing, and other possible asthma tests. This will allow you to have a firm understanding of your breathing problems and will be the basis for the suggested plan of asthma treatment.

For more detail, see WebMD’s article Asthma Tests.

Your doctor may use one or more of the following asthma tests in diagnosing asthma. These tests are used to assess your breathing and to monitor the effectiveness of asthma treatment.

Spirometry -- a lung (or pulmonary) function test that measures how much air you can exhale. This asthma test confirms the presence of airway obstruction that improves with treatment, which is very characteristic of asthma, and can accurately measure the degree of lung function impairment. This test can also monitor your response to asthma medications and is recommended for adults and children over age 5.

For more information, see WebMD's Pulmonary Function Tests.

Peak Flow Testing -- a self-assessment you can do at home to evaluate lung function. The peak expiratory flow rate (PEFR) provides a reliable objective measure of airway function. Your doctor will go over how to use a peak flow meter, which involves taking a deep breath and blowing out as hard as you can. Peak flow is the highest airflow velocity that you can achieve. When done accurately, a drop in the peak flow measurement reflects an obstruction in your airways. While peak flow is less accurate than office spirometry for monitoring of lung function, peak flow monitoring at home can help you manage your symptoms at home and help indicate when an asthma attack may be approaching.

For more information, see WebMD’s Using a Peak Flow Meter.

Chest X-Ray -- while not routinely required, if there are symptoms that may be caused by another condition such as pneumonia, your doctor may want to do a chest X-ray. Or, if your asthma treatment is not working as well as it should, a chest X-ray may help to clarify the problem.
