From: Liquid chromatography/mass spectrometry analysis of exhaled leukotriene B4 in asthmatic children
Leukotriene (LT) B 4 concentrations in exhaled breath condensate in children with allergic disease. Exhaled LTB4 concentrations in healthy children (open squares), atopic non-asthmatic children (NA) (filled squares), steroid-naïve atopic asthmatic children (open triangles), and steroid-treated (ST) children with atopic asthma (filled triangles). LTB4 values are expressed as picograms produced during 15 minutes of breathing. Median values are shown with horizontal bars.
