Fractional exhaled Nitric Oxide (FeNO) testing gives a fast, non-invasive measure of airway inflammation — essential for confident asthma diagnosis and monitoring.
FeNO testing measures the level of nitric oxide in a patient’s breath, a reliable marker of eosinophilic airway inflammation. It helps clinicians diagnose asthma, guide inhaled-steroid therapy and monitor adherence — all from a simple, non-invasive breath test.
Medi-Diag Africa supplies handheld and desktop FeNO devices to clinics and respiratory practices, complete with training, consumables and support so you can integrate FeNO into routine care immediately.
