There is evidence to suggest that H. pylori moves proximal in the stomach in patients on therapy with proton pump inhibitors, and, as such, samples from the fundus and body should be taken in these patients. Active gastrointestinal bleeding reduces accuracy of the test. The specificity and sensitivity of this test is high compared with urea breath test. The test is often done as part of point-of-care diagnostics, to eliminate the time and expense required to detect H. pylori on pathology testing.
