If you already know that you have asthma or allergies, a screening can help you find out if your condition is under control.

In addition to asthma and nasal allergies, you can find out if you have exercise-induced bronchoconstriction, or EIB (also known as exercise-induced asthma) — breathing problems that occur during or after exercise.


Find an allergist

What happens at an asthma screening?

First, you’ll fill out registration forms that ask for basic information, including your name and age, and answer questions about your symptoms. Children ages 8 to 14 get a form they can fill out themselves; parents complete the form for children younger than 8.

Next, you’ll take a breathing test. It doesn’t hurt at all; you just blow very hard into a tube. The tube is connected to a computer that measures lung volumes and flow rates to tell how well your lungs are functioning.

Finally, you’ll speak with an allergist to review the results of your breathing test and go over your answers to the questions on the registration form. The allergist may want more information about your symptoms. If the results suggest that you might have asthma, nasal allergies or EIB, the allergist will refer you for diagnosis. For those individuals who already know they have asthma, the asthma screening will determine whether their asthma is well-controlled. You may be instructed to follow up with an allergist to achieve control of your asthma.

The asthma screening takes about 15 minutes.

In the meantime, take the Asthma and Allergies Symptom Test to find out if you might have allergies or asthma. Your results will point you toward resources to help you feel good all day and sleep well at night.
