How do i know if my child has asthma?

Symptoms, tests: Symptoms of pediatric asthma are cough, wheeze, and/or difficulty breathing/shortness of breath that is recurrent and commonly triggered by colds, exercise, cold air and at night. If over 5 yrs old a breathing test called spirometry will be done. Albuterol that treats asthma can be used and if symptoms improve, that is suggestive. Chest x-ray usually normal. Allergies commonly coincide.
