Urea Breath Test (UBT) With Breath Hp System /BreathID Hp Lab System Pediatrics

Pediatric subjects with indication for H.pylori testing, will be tested with both stool antigen as a reference standard and a urea breath test using the BreathID® Hp and BreathID® Hp Lab Systems. The BreathID® Hp system continuously measures breath via a nasal cannula and the BreathID® Hp Lab System measures breath collection bags before and after ingestion of a solution with enriched carbon 13 urea and citric acid. The stool sample will be provided within a week of the breath tests and will be analyzed by a central laboratory. Safety and overall efficacy will be assessed.
