Croup: Tests and Diagnosis

What tests are used to diagnose croup?

Tests are not necessary to diagnose croup unless doctors suspect another condition is causing your child's symptoms. This can sometimes be the case because if the inflammation has an unusual presentation or unusual response to traditional croup treatments.

If your child has the warning signs listed on the overview page, other tests may be done to look for other causes of stridor.

How do providers at Children's Hospital Colorado make a diagnosis?

Doctors can usually diagnose croup by listening for the telltale barking cough and stridor. They will also ask if your child has had any recent illnesses with a fever, runny nose and congestion, and if your child has a history of croup or upper airway problems.
