Nitric oxide testing

Many patients who complain of asthma-like symptoms, particularly chest tightness and cough, undergo breathing tests which are found to be completely normal.    Patients are often told that they do not have asthma and are treated for other conditions instead.  In this situation, a new diagnostic test which measures the amount of nitric oxide in exhaled air (called “Niox”), may be extremely helpful.  Over the past 5 years, we have evaluated hundreds of patients with the Niox test, allowing us to more accurately diagnose and treat these individuals.  If you have chronic, undiagnosed chest symptoms, this new technology may help to determine what is going on.
