What Are Common Ways to Diagnose Asthma?Personal and medical history. We will ask you questions about your symptoms and the possible causes of those symptoms. If you keep a journal of your symptoms, please bring it along with you.

Common Asthma Tests
What is a Lung function Test?Lung Function Tests simply measure your breathing that are performed before and after inhaling a medication known as a bronchodilator (bron-co-DIE-a-later) which opens your airways. If we detect that your lung function improves a lot with use of a bronchodilator, you probably have asthma.
Common Lung Function Tests Used to Diagnose AsthmaSpirometry During Spirometry, you breathe into a mouthpiece that measures the amount of air you’re able to breathe in and out and its rate of flow. You will take a deep breath and then exhale forcefully. Peak airflow You will breathe into a small, handheld device to measure the rate at which you can force air out of your lungs. You'll be asked to breathe in as deeply as you can and then blow into the device as hard and fast as possible. Asthma patients also use a Peak Flow Meter at home to help track their condition. Trigger tests If your other results are normal, but you’ve been experiencing signs and symptoms of asthma, we may test you with known asthma triggers to provoke a mild reaction. If you don’t have asthma, you won’t react. But if you do have asthma, you likely will develop asthma symptoms. We may prescribe a trial dosage of asthma medication to see if it helps your condition.
Do We Test for Other Conditions?If we think you may be affected by something other than asthma or besides asthma, we may run other tests. These might include a chest X-ray, acid reflux test, sinus X-rays or allergy tests*. *Allergy tests aren’t used to determine if you have asthma. But, if you have allergies, they may be causing your asthma.
