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.

Indication for H.Pylori Testing
Walk in basis: Symptomatic patients of H.pylori infection will be enrolled for this study if all acceptance criteria are met. Patients will undergo C13 Urea Breath Test in addition to at least 2 other diagnostic tools from one obtained biopsy as comparison. PyloPlus UBT System: Breath will be analyzed for change in carbon 13 content in breath after ingestion of enriched carbon 13 urea. Histology: Biopsy specimen fixed with 10% buffered formalin were cut into 4mm sections, stained with Giemsa stain, and examined by experienced pathologist Rapid Urease Test: Biopsy specimen obtained and placed onto Rapid Urease Test H.pylori Culture: Biopsy specimen obtained and sent to lab for culture analysis
