H. Pylori Infection
Conditions
Brief summary
An open-label, comparative group study to evaluate the equivalency of the PyloPlus 13C Urea Breath Test to predicate devices on the market.
Detailed description
An open-label, comparative group study to evaluate the equivalency of the PyloPlus 13C Urea Breath Test to predicate devices on the market. Predicate devices include: Histology, Culture, RUT, and other 13C Breath Tests.
Interventions
Breath will be analyzed for change in carbon 13 content in breath after ingestion of enriched carbon 13 urea.
Biopsy specimen fixed with 10% buffered formalin were cut into 4mm sections, stained with Giemsa stain, and examined by experienced pathologist
Biopsy specimen obtained and placed onto Rapid Urease Test
Biopsy specimen obtained and sent to lab for culture analysis
