Term Description

The fractional concentration of exhaled nitric oxide, or FeNO, is used to assess the amount of inflammation present in the lungs. Inflammatory cells produce NO, so higher levels of NO indicate the presence of inflammation. The FeNO test is used to help diagnose allergic or eosinophilic asthma as well as monitor treatment efficacy. https://www.aaaai.org/conditions-and-treatments/library/asthma-library/feno-test

Part Description

LP173640-6   Nitric oxide
In medicine, exhaled nitric oxide (eNO) can be measured in a breath test for asthma or other conditions characterized by airway inflammation. Nitric oxide (NO) is a gaseous molecule produced by certain cell types in an inflammatory response. The fraction of exhaled NO (FENO) is a promising biomarker for the diagnosis, follow-up and as a guide to therapy in adults and children with asthma. The breath test has recently become available in many well-equipped hospitals in developed countries, although its exact role remains unclear.
