What Is FeNO Testing?

Fractional exhaled nitric oxide (FeNO) testing is a simple breathing test that measures airway inflammation. People with certain types of asthma often have elevated nitric oxide levels in their breath because inflamed airway cells release this gas.

During the test, you breathe slowly and steadily into a handheld device that measures nitric oxide concentration. The process takes only a few minutes and does not involve needles, medications, or radiation.

FeNO testing provides valuable information that helps physicians determine:

• Whether airway inflammation is present
• If asthma is likely causing symptoms
• Whether inhaled corticosteroid medications may help
• How well current asthma treatments are working

Because FeNO specifically measures eosinophilic airway inflammation, it is particularly useful for identifying patients who will respond well to anti-inflammatory asthma medications.

Why FeNO Testing Is Important for Asthma Diagnosis?

Asthma can sometimes be difficult to diagnose because symptoms overlap with other respiratory conditions. Traditional breathing tests measure airflow but may not always detect inflammation in the airways.

FeNO testing adds an important layer of diagnostic information by directly measuring airway inflammation. This allows physicians to identify asthma earlier and develop more targeted treatment plans.

Benefits of FeNO testing include:

• More accurate asthma diagnosis
• Identification of inflammation even when lung function appears normal
• Reduced trial-and-error when prescribing medications
• Improved monitoring of asthma control

By combining FeNO testing with pulmonary function testing, doctors can better understand both airway inflammation and lung function.

Conditions FeNO Testing Helps Evaluate

FeNO testing is most commonly used for patients with suspected or known asthma, but it can also provide helpful insights for other respiratory conditions.

Your provider may recommend FeNO testing if you have:

• Persistent coughing or wheezing
• Shortness of breath during exercise
• Difficulty controlling asthma symptoms
• Frequent asthma flare-ups
• Symptoms that do not improve with treatment

The test is especially helpful for determining whether symptoms are related to eosinophilic airway inflammation, a common asthma subtype that responds well to steroid therapy.

How FeNO Testing Helps Guide Asthma Treatment

One of the most important benefits of FeNO testing is its ability to help physicians personalize asthma treatment.

FeNO results help doctors determine:

Whether inhaled corticosteroids will work

High nitric oxide levels often indicate inflammation that responds well to steroid medications.

If asthma medication is working

Lower FeNO levels after treatment usually indicate that airway inflammation is improving.

If medication adjustments are needed

Persistently elevated levels may indicate the need for a different treatment strategy.

If biologic therapies may be beneficial

Patients with severe inflammation may qualify for advanced biologic medications designed for certain asthma types.

By measuring airway inflammation directly, FeNO testing helps physicians avoid unnecessary medications and focus on treatments that work best for each patient.

How long does FeNO testing take?

The entire test typically takes only a few minutes, and results are usually available immediately during your appointment.

Who should have FeNO testing?

FeNO testing may be recommended for patients with suspected asthma, persistent cough, wheezing, or difficulty controlling asthma symptoms.

Can FeNO testing diagnose asthma?

FeNO testing helps support an asthma diagnosis by measuring airway inflammation, but it is typically used alongside other tests such as pulmonary function testing.

Do I need to prepare for FeNO testing?

Patients may be asked to avoid eating, smoking, or exercising for about an hour before the test to ensure accurate results.

How often should FeNO testing be repeated?

Some patients may have repeat testing during follow-up visits to monitor airway inflammation and evaluate how well asthma treatments are working.

Frequently Asked Questions – COPD & Asthma Care in Vienna, VA

What is the difference between COPD and asthma?

COPD (Chronic Obstructive Pulmonary Disease) and asthma are both chronic lung conditions that affect breathing. COPD is usually caused by long-term exposure to lung irritants such as cigarette smoke and tends to worsen over time. Asthma is caused by airway inflammation and can be triggered by allergens, exercise, cold air, or respiratory infections. Both conditions require proper diagnosis and management by a pulmonary specialist.

What are the early symptoms of COPD?

Early symptoms of COPD often include shortness of breath during activity, persistent coughing, wheezing, chest tightness, and increased mucus production. Some patients also experience frequent respiratory infections or fatigue. Early diagnosis and treatment can help slow the progression of COPD.

What are the most common asthma symptoms?

Asthma symptoms may include wheezing, shortness of breath, coughing (especially at night or early morning), and chest tightness. Symptoms may worsen when exposed to allergens, smoke, pollution, cold air, or during exercise.

How are COPD and asthma diagnosed?

Pulmonary specialists diagnose COPD and asthma using a combination of medical history, physical examination, and lung function testing. Common diagnostic tests include spirometry, pulmonary function testing (PFT), and imaging studies to evaluate lung health and breathing capacity.

What treatments are available for COPD and asthma?

Treatment depends on the severity of the condition but may include inhalers, bronchodilators, corticosteroid medications, nebulizer treatments, pulmonary rehabilitation, and lifestyle modifications such as smoking cessation and avoiding triggers.

When should I see a pulmonologist for breathing problems?

You should see a pulmonologist if you experience persistent coughing, wheezing, shortness of breath, frequent respiratory infections, or difficulty breathing during normal activities. Early evaluation can help diagnose COPD, asthma, or other lung conditions.

Can COPD or asthma be cured?

Neither COPD nor asthma currently has a cure, but both conditions can be effectively managed with proper medical treatment and lifestyle adjustments. Many patients are able to control symptoms and maintain a normal, active lifestyle with the right care plan.
