    My son has had these tests done several times. He started doing them annually when seeing a specialist. The test itself is very simple. My son sat in an enclosed area, kind of like a big tube with a chair and a breathing machine. He was told to breathe in slowly and deeply. After that they tested his breathing doing a normal pulmonary function test while he was enclosed in the tube. We then had to wait 20 minutes and then use albuterol. Again we waited ten minutes and another pulonary function test was given. He was in the tube for total of 5-10 minutes, depending on how he handled the test that day.

    My allergist now has me do these -- I've done it twice. It has to be done fasting, in the morning, because apparently food affects the results. It's just blowing into a device for a minute or two. Really not even as hard as spirometry. My understanding is that measuring exhaled NO is a way of measuring lung inflammation, whereas spirometry measures the amount of lung constriction/obstruction (narrowing of air passages).

    Hope this helps. My insurance covered it without a problem. Take care & good luck. Judy
