Trial treatment
Your healthcare professional may do a trial treatment with an inhaled medicine that opens airways. This medicine acts quickly. A diagnosis of asthma is more likely if symptoms improve within the time the medicine is expected to work.
A treatment trial may be especially helpful for diagnosing asthma in young children who cannot do a lung test.
