Asthma test can diagnose a chronic cough
US Mayo Clinic researchers have advised that a diagnostic asthma test – known as the exhaled nitric oxide test – is a cheap way to tell if inhaled corticosteroids will help a chronic cough.
The nitric oxide test is very accurate but underused and could be used upfront on all patients complaining of chronic cough, thereby saving time and costs in running other tests and bringing treatment and relief to the patient in the least invasive, fastest way possible.
