What this trial studies

This is a multi-center, non-randomized, open-label study aimed at evaluating the safety and efficacy of the PyloPlus Urea Breath Test System in pediatric patients aged 3 to 17. Participants will undergo testing with non-radioactive 13C-Urea and submit stool samples for analysis. The results from the PyloPlus Analyzer will be kept blinded from the investigators and treating physicians to ensure unbiased patient management decisions. The study is expected to last approximately six months, with subjects enrolled on a walk-in basis.

Who should consider this trial

Good fit: Ideal candidates for this study are children aged 3 to 17 who have not received H. Pylori treatment in the past four weeks.

Not a fit: Patients who are pregnant, lactating, or have certain medical conditions that could compromise their safety or data quality will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a safer and more effective method for diagnosing Helicobacter Pylori in children.

How similar studies have performed: Other studies have shown success with breath tests for H. Pylori, but the specific use of the PyloPlus UBT System in this population is novel.
