R-Tube


Capture Airway Biomarkers Whenever and Wherever Symptomatic Episodes Occur

Changes in the lung happen rapidly and exacerbations can occur at any time. Only the RTube™ captures the vital data you need by being available for the subject to use during symptomatic episodes, any time, any place. Unsupervised patients can easily collect samples in their home and send them through the mail to you or to our central laboratory for analysis. Over 75,000 collections have been taken non-invasively using this system making it the premier solution for Exhaled Breath Condensate collection, transport and storage. 

What is Exhaled Breath Condensate?

Exhaled Breath Condensate (EBC) is the exciting new method of simply and safely capturing breath samples for non-invasive assessment of airway inflammation, chemistry, and evidence of airway acid exposure and production. These breath samples contain Airway Lining Fluid (ALF) evolved by turbulence from the airway wall as well as condensed water vapor and soluble volatiles. Dozens of inflammatory and chemical compounds have been identified in EBC samples that have helped us to better understand lung disease and create new diagnostic tools.
