How you prepareBy Mayo Clinic staff
Check ahead of time to see whether nitric oxide testing is covered by your insurance.
To make sure test results are accurate, you will need to avoid the following for at least two hours before you take the test:
- Using an asthma inhaler
- Eating and drinking
- Using tobacco, toothpaste or mouthwash
