The following tests are available at Allergy West in our office located at 133 Littleton Road, Westford, MA.

Exhaled nitric oxide is a gas that is produced by inflamed airways. Airway inflammation is one of the hallmarks of asthma. NIOX measures exhaled nitric oxide, and tells us how much inflammation is currently present in a patient’s airways.
