Study summary

The purpose of this study is to compare between the POCone® to the UBiT®-IR300 in measuring 13CO2/12CO2 ratio in breath samples when used together with the BreathTek® UBT (urea breath test) Kit and the pUHR-CA web-based software program in identifying H. pylori infection in pediatric subjects.

Read the detailed description

The same patients will be tested on both the POCone® and UBiT®-IR300. If the patients test positive for H. pylori, they will be given eradication medication and brought back in for a re-test.

What researchers measure

Primary outcomes

  1. Agreement Between POCone and UBiT-IR300.

    The study end-points are UHR values derived from DOB (delta over baseline) values obtained from the POCone and UBiT-IR300 (UHRP and UHRU, respectively) at Baseline and Post-Dose. Same patients will be tested on both the POCone and UBiT-IR300. Subjects fasted for at least 1 hr prior test. Each patient provided breath samples in 3 blue (Baseline) breath bags-labeled "A" "B" "C". Subjects were given Pranactin-Citric solution (4oz) to drink, waited 15 min and collected 3 pink (post-dose) bags which were paired with the baseline bags in no particular order. Each pair was tested on both machines. The first two available pairs of UHR values were used for data analysis. The 3rd pair was used only if one of the first two samples did not produce a valid test result. DOB values were generated by the two instruments for each Baseline and Post Dose pair. UHR values were claculated based on the DOB values and the subject's anthropometric variables (age, gender, ehight and body weight).

    Time frame: Baseline, Post Dose (15 min)

Other outcomes

  1. Number of Participants Tested Positive/Negative for H. Pylori

    Qualified subjects from clinical sites underwent a standard urea breath test using the BreathTek UBT Kit. Breath samples were analyzed using both the POCone and the UBiT-IR300. DOB values from these two infrared spectrophotometers were converted to respective UHR values using pUHR-CA. The paired UHR values from each subject were evaluated for agreement. UHR values of \>10 µg/min were considered positive for H. pylori and UHR values of \<10 µg/min were considered negative for H. pylori.

    Time frame: Single Study Visit (1 hour of testing)

The record gives a start of Jul 2012, a primary completion of Mar 2013 and a completion of Apr 2013. It does not say whether these dates are actual or estimated.

Results were first posted in Jan 2015, 1 year 10 months after primary completion.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Feb 23, 2015, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
