Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a prospective study designed to acquire and bank human specimens from subjects who are scheduled for routine upper endoscopy for symptoms such as dyspepsia. This study will be conducted at a minimum of 2 sites in the United States. Investigator sites will enroll prospective subjects who meet the inclusion / exclusion criteria. A case report form (CRF) provided by the sponsor will be used to capture basic demographic information (DOB, age, gender, race/ethnicity), medication history, and related clinical information. The CRFs will also record the results of the following tests performed with the gastric biopsy tissue specimens: histology and rapid urease test (RUT).
