"The RTube™ has become a vital part of our asthma research program. We have found that even pre-school children can collect and store breath condensate with the RTube at home, a method that is not feasible with other collection systems.

In a recent study, we were able to obtain breath condensate with the RTube in over 50 children with acute exacerbations of asthma in the hospital. This would not be possible with a stationary collection device."

"... the RTube is well suited for collection of condensate from multiple people within a short period of time. Also, there is little technical training needed to supervise the collection of condensate with the R-Tube. Though the system is still a challenge to breathe through for the extremely frail and infants due to the one-way valve, we were still able to collect condensate from over 85% of our population sample (ranging in age from 3 months to 93 years old). For the purposes of rapid assessment of airway inflammation via the indicator of airway acidity, we found that the R-Tube was a good choice for our public health emergency application. I appreciate how supportive RRI has been of our work in Graniteville, and hope that we can continue working together to monitor the lung health of this population."
