Fractional Exhaled nitric oxide (FeNO) is a quantitative, non-invasive and simple method of measuring airway inflammation that provides a complementary tool to other established methods of assessing airways disease in asthma patients.
Specifically, FeNO is an objective measurement of allergic/eosinophilic inflammation. This type of airway inflammation results from the activation of mast cells and antigen-specific T-helper cells type 2 (Th2) resulting in the production of cytokines including interleukin (IL)-4, IL-5, and IL-13.3
