The Study of Exhaled Breath Condensate pH

Exhaled Breath Condensate pH is one of the most validated biomarkers in EBC.  There are many publications linking low EBC pH to various lung diseases and offering reasons to consider pH as part of an exhaled biomarker study.  We won’t be exploring the “why” here; just... read more
