FeNO Testing

FeNO testing measures the level of nitric oxide in your breath, which helps assess airway inflammation often associated with asthma. During the test, you inhale deeply and then exhale steadily into a device that analyzes the nitric oxide levels. Elevated FeNO levels can indicate inflammation in the airways, guiding doctors in diagnosing asthma and tailoring treatment. It’s a quick, non-invasive, and painless procedure that provides valuable information about airway health, helping to differentiate asthma from other respiratory conditions and monitor response to therapy.
