Hi. Yesterday when I went to my second opinion asthma specialist she gave me a FeNO (fractional exhaled nitric oxide) test. I have never had this test before. It measures the level of inflammation in you lungs. I was surprised to learn that it is not a new test. I'm wondering why my allergist/asthma specialist and my pulmonologist have never given me this test.
Have you had a FeNo test?
Do you have a FeNO test every time you see your asthma doctor?
If you have had a FeNO test, does your doctor use the information to adjust your medication?
