Storage conditions for stability of offline measurement of fractional exhaled nitric oxide after collection for epidemiologic research

The measurement of fractional concentration of nitric oxide in exhaled air (FeNO) is valuable for the assessment of airway inflammation. Offline measurement of FeNO has been used in some epidemiologic studies. However, the time course of the changes in FeNO after collection has not been fully clarified. |
