Treating asthma in children ages 5 to 11

Tests to diagnose and monitor asthma

For children 5 years of age and older, healthcare professionals can find and track asthma with the same tests used for adults. These include spirometry and peak flow meters. They measure how much air your child can quickly force out of the lungs. That provides a sign of how well the lungs are working.

If your child's usual breathing seems regular, other tests might be done to find out if your child has asthma. Breathing might be measured before and after exercising. Breathing may also be measured after breathing in cold air or a medicine called methacholine. These kinds of tests are known as bronchoprovocation challenges.

Other tests that your child's healthcare professional may recommend include a chest X-ray and allergy testing.
