Exhaled breath condensate (EBC) is composed mainly by water and also contains non-volatile mediators, which are expired in small droplets of airway fluid. Urea has been proposed as a normalization factor for EBC non-volatile biomarkers. Aim of this study was to assess volatility and diffusivity of urea ex vivo and to measure its EBC concentrations in different clinical conditions. Volatility was assessed quantifying EBC concentrations collected at 4 different temperatures, whereas diffusivity… CONTINUE READING
