What is a Fractional exhaled nitric oxide(FENO) Test in Delhi ?
What is Fractional exhaled nitric oxide(FENO)?
Fractional exhaled nitric oxide (FeNO) measures the level of nitric oxide gas in the breath. Nitric oxide rises when the airways are inflamed, especially with certain types of allergic inflammation. Physical examination provides clues; a test result removes ambiguity and allows targeted, evidence-based management to begin promptly.
What does Fractional exhaled nitric oxide(FENO) measure?
This test helps detect and monitor airway inflammation linked to asthma and other allergic lung conditions. Doctors use FeNO to support asthma diagnosis, to see if inhaled steroid treatments are working, and to help predict the risk of flare-ups. The test is quick, noninvasive, and often used alongside symptoms, lung function tests, and medical history to guide treatment choices.
What symptoms suggest Fractional exhaled nitric oxide(FENO) may be needed?
A doctor may recommend Fractional exhaled nitric oxide(FENO) when a patient reports any symptom your doctor has identified as requiring objective laboratory investigation , including unexplained fatigue, unexplained weight change, persistent pain, fever, or abnormal bleeding. Sample collection for Delhi is available at labs and at home across Hauz Khas, South Extension, and surrounding neighbourhoods.

Why Take a Fractional exhaled nitric oxide(FENO) Test in Delhi ?
When does a doctor order Fractional exhaled nitric oxide(FENO)?
Fractional exhaled nitric oxide(FENO) is commonly used in asthma evaluation and monitoring panels to assess airway inflammation. It may be ordered when a patient has cough, wheeze, chest tightness, or unexplained breathlessness.
Who should get Fractional exhaled nitric oxide(FENO) done in Delhi?
Delhi's 30+ million population, India's most severe urban air pollution, one of the country's highest combined diabetes and cardiovascular disease burdens, extreme seasonal temperature range (from 3°C in January to 48°C in May), and monsoon infection risk across Dwarka, Rohini, Shahdara, and Uttam Nagar make regular preventive diagnostic testing an essential part of health management for all city residents. Genetic testing benefits people with a family history of an inherited condition, couples planning a pregnancy, and patients whose symptoms suggest a genetic cause. GetVisit coordinates sample collection for residents of Uttam Nagar, Greater Kailash, and across Delhi, with results guiding specialist and family decisions.
What conditions can Fractional exhaled nitric oxide(FENO) help diagnose?
The test helps diagnose allergic or eosinophilic asthma and guides decisions about inhaled steroid use. Elevated or low results may reflect allergies, infections, smoking, or medication effects, and family history of asthma raises its relevance.
What do Fractional exhaled nitric oxide(FENO) results mean?
Higher or positive results: A high FeNO (fractional exhaled nitric oxide) indicates airway eosinophilic inflammation, often seen in allergic or steroid‑responsive asthma. Your doctor reads the value against the reference range on your report and your symptoms, and may repeat a borderline result to confirm it.
How often should Fractional exhaled nitric oxide(FENO) be repeated?
For preventive screening with a normal baseline: annually for most adults above 35. For monitoring a known condition: at the interval your specialist recommends , typically every 3 to 6 months for active conditions and annually for stable, well-controlled ones.
What happens after Fractional exhaled nitric oxide(FENO) results are ready?
You will be notified the moment results are ready, usually the same day for routine tests. Open the report in the GetVisit app to see each value beside its reference range, share it with your doctor in a tap, or book a specialist consultation to talk it through.
