Abstract
The recent paper by Rosias et al. 1 reported that silicone and glass inner coatings were superior to the EcoScreen® system (Erich Jaeger GmbH, Hochberg, Germany), aluminium, polypropylene and Teflon when measuring 8-isoprostane and albumin levels in exhaled breath condensate (EBC) 1–3. This raises important issues in the ongoing debate about the optimal collection method for sampling airway biomarkers. We have complemented these important data by comparing the efficiency and reproducibility of EBC biomarkers collected by different devices in six healthy subjects.
