| Biomarkers provide important diagnostic and prognostic information on heterogeneous diseases such as
chronic obstructive pulmonary disease (COPD). However, finding a suitable specimen for clinical analysis
of biomarkers for COPD is challenging. Exhaled breath condensate (EBC) sampling is noninvasive, rapid,
cost-effective and easily repeatable. EBC sampling has also provided recent progress in the identification
of biological macromolecules, such as lipids, proteins and DNA in EBC samples, which has increased its
utility for clinical scientists. In this article, we review applications involving EBC sampling for the analysis
of COPD biomarkers and discuss its future potential |
