Fraction of Exhaled Nitric Oxide (FeNO)
A test that measures the level of nitric oxide gas in an exhaled sample of your breathe
Indications for Testing:
NIOX VERO Airway Inflammation Monitor NIOX VERO® measures Nitric Oxide (NO) in the breath. Nitric Oxide is frequently elevated in some airway inflammatory processes, such as asthma. The fractional NO concentration in expired breath (FeNO), can be measured by NIOX VERO. This test will be used in conjunction with other tests and to find the cause of your symptoms.
What to expect during this procedure:
The measurement of FeNO by NIOX VERO is a quantitative, non-invasive, simple and safe method to measure the FeNO concentration. The procedure consists of a short breathing test guided by a Respiratory Therapist.
The FeNO test is a crucial tool in respiratory medicine because it provides quick, objective, and quantitative data on airway inflammation. It enables better diagnosis, personalized treatment, and improved asthma management, reducing exacerbations and unnecessary medication use.
