Description: Stool antigen tests have been recommended by both the American Gastroenterological Association (AGA) and the American College of Gastroenterologists (ACG) as the most accurate non-invasive tests for diagnosis and for confirmation of eradication.1,2 This method is highly sensitive and specific and useful for diagnosis, therapeutic monitoring, and test of eradication.

Unlike stool antigen tests, Serology-based methods have a sensitivity and specificity of only 90% and cannot distinguish between active and resolved infection.3,4 Thus, serology tests are not recommended by the AGA for initial diagnosis of H pylori infection.4 Furthermore, they are not recommended by either the AGA or the ACG for monitoring infection or confirming eradication of the organism.
