Diagnosing EIB can be hard because coughing and shortness of breath have many causes. An allergist is a doctor with special training and expertise in treating allergies, asthma, and other breathing problems. The allergist will:

• ask questions about your health and your symptoms
• do a physical exam.
• give a test called spirometry that measures how much air you can breathe out after taking a deep breath.

The allergist may also order a chest X-ray, blood tests or allergy tests. Sometimes the allergist may do tests that measure how well your lungs are working before and after you exercise.
