FENO TESTS FOR ASTHMA

Asthma makes breathing more difficult, and it also has symptoms similar to several other respiratory conditions. Some people have both asthma and another respiratory issue. If you’ve not yet been diagnosed with asthma, a FeNO test can help determine what’s causing your symptoms and either confirm or rule out asthma. FeNO stands for fractional exhaled nitric oxide, and it’s used to measure the amount of nitric oxide in your breath, which helps doctors determine if and how much your airways are inflamed. If you’ve already been diagnosed with asthma, tracking FeNO levels can help determine what kind of asthma you have and whether your medications are working or need adjusting. The test is quick, non-invasive, and results are available immediately.

P.S. A FeNO test can tell if you are a good candidate for using corticosteroids to manage asthma. It can also show your doctor if you’ve been using your medications correctly.
