Nitric Oxide Test
The Nitric Oxide Test, also known as fractional exhaled nitric oxide (FeNO) test, is a non-invasive test that measures the amount of nitric oxide gas in the exhaled breath.
The test helps guide treatment for those with asthma
The Nitric Oxide Test is a quick diagnostic test used to measure the amount of nitric oxide gas in a person's exhaled breath. Nitric oxide is produced by cells lining the respiratory airways and its level is considered a biomarker for inflammation in the airways. Inflammation in the airways is a characteristic symptom of asthma, which is a chronic respiratory disease that causes inflammation and narrowing of the airways.
The FeNO test can help in the diagnosis and management of asthma by measuring the level of inflammation in the airways, and assessing the effectiveness of asthma treatment.
The test benefits
The Nitric Oxide test can provide valuable information to healthcare professionals to help diagnose and manage various respiratory conditions. Here are some of the benefits of the FeNO test:
- Non-invasive and painless test.
- Quick and easy to perform.
- Can help diagnose and manage asthma.
- Can help monitor asthma treatment effectiveness.
- May help identify patients who can benefit from inhaled corticosteroid treatment.
When is it needed to perform?
This test is primarily used to evaluate airway inflammation and to diagnose and manage asthma.
Asthma diagnosis
FeNO test helps in the diagnosis of asthma in individuals with respiratory symptoms.
Monitoring asthma
The test can also help monitor asthma and its response to treatment.
Evaluation of airway inflammation
The FeNO test can evaluate the level of inflammation in the airways, which can help guide treatment decisions.
Personalized treatment
FeNO test can aid in personalized treatment planning for patients with asthma.
Rule out other respiratory conditions
The test can also help rule out other respiratory conditions that have similar symptoms to asthma, such as chronic obstructive pulmonary disease (COPD) or respiratory infections.

What are the procedural steps?
The patient will breathe into a tube connected to a machine that measures the level of nitric oxide in their breath. This is a painless and non-invasive procedure. The test typically takes less than 10 minutes to complete.
Patient preparation
The patient will be asked to avoid certain foods, medications, and activities that can affect the results of the test.
Exhale into the device
The patient will be asked to exhale slowly and steadily into the device, which measures the amount of nitric oxide in the breath.
Repeat the test
The test may be repeated several times to ensure the accuracy and consistency of results.
Test results
The test results are usually available immediately, and we will interpret the results and discuss them with the patient.
Follow-up
The patient is advised on changes or further testing or treatment.

Interventional Pulmonology is generally considered safe when performed by a trained and experienced specialist. As with any medical procedure, there are risks involved, but the benefits of minimally invasive techniques can often outweigh these risks.
Many Interventional Pulmonology procedures can be performed with local anesthesia, which means patients are awake during the procedure. However, some procedures may require general anesthesia, which will be discussed with the patient beforehand.
Recovery time can vary depending on the type of procedure performed and the patient's overall health. Many patients are able to return home on the same day as the procedure, and full recovery can take anywhere from a few days to several weeks. The specialist will provide specific instructions for post-procedure care and follow-up appointments to monitor progress.
Most Interventional Pulmonology procedures are minimally invasive and cause minimal discomfort. Patients may experience some mild pain or discomfort during the procedure or in the hours immediately following, but this can often be managed with pain medication.
Many Interventional Pulmonology procedures can be performed on an outpatient basis, which means patients can return home on the same day as the procedure. However, some procedures may require a short hospital stay for observation and monitoring.
