Diagnostics of Helicobacter pylori Infection in Patients with Peptic Ulcer Bleeding

In peptic ulcer bleeding, RUT combined with histology is an adequate diagnostic approach. However, false negative results have to be considered following even short-term HpSuT or hospitalization. Non-invasive diagnosis based on serology alone is inaccurate and should be complemented by the urea breath test prior to starting HpSuT.
