Biomarkers Vital to the Study and Diagnosis of Acute Airway
Disease with the RTube™
Only the RTube captures the vital biomarker data
you need by being available for the subject to use during symptomatic
episodes, any time, any place. Monitoring acute airway disease
with the RTube allows the capture of biomarkers during exacerbations
when the data are most relevant. Our new Single-Subject Longitudinal
Airway pH Monitoring Kit provides researchers with the ability
to monitor a subject's airway pH and other
biomarkers immediately upon onset of symptoms, regardless
of where or when they occur, and allows you to follow the subject
longitudinally over a course of eight symptomatic events. Airway
pH homeostasis is poor in respiratory disease, and this is
identified most readily by sequential sample collections. Collecting
multiple samples over a set period of time, and immediately
after symptoms, maximizes the value of your biomarker data
by allowing direct association with specific transient symptoms.
Collecting EBC is as easy as breathing through a nebulizer.
The subject exhales normally into the RTube while the moisture
from their breath is condensed in the collection chamber. After
collection, the chamber is sealed, stored locally, or transported
to a lab for analysis. At the lab our unique internal one-way
valve is used as a syringe that gathers droplets adhering to
the inside wall into a sample pool near the top of the RTube
where it can easily be removed and analyzed.
Select the RTube Specialty Kit that is Right for You
We offer three Specialty Kits: the 25-Collection
Starter Kit, the 100-Collection Starter Kit, and the Single-Subject
Longitudinal Sampling Kit. Each kit is optimized for a specific
25-Collection Starter Kit
This is our lowest-cost general-purpose kit. Perfect for
pilot studies and investigators new to EBC, this kit provides
everything you need to collect and store 25 EBC samples.
100-Collection Starter Kit
This kit provides everything you need to start and complete
a small to mid sized study. In addition to a larger number
of collection devices, this kit provides an additional cooling
sleeve to enable back to back or simultaneous sample collections.
This kit is our most popular and is especially useful when
performing a large number of consecutive collections in a
school or workplace setting.
For larger studies, we also offer bulk restocking supplies.
