FeNO

Fractional Exhaled Nitric Oxide (FENO) testing measures the level of nitric oxide in the breath, which can indicate airway inflammation. Dr. Mayank recommends FENO testing in diagnosing and monitoring asthma. Elevated levels of nitric oxide may suggest poorly controlled asthma or allergic inflammation. FENO is a non-invasive test that helps tailor asthma treatment and provides a quick, reliable assessment of inflammation in the airways.
