Abstract
OBJECTIVES: Current guidelines recommend either the urea breath test (UBT) or the Helicobacter pylori antigen stool test (HpSA) for monitoring H. pylori infection. The aim of this study was to evaluate the agreement between the two tests in patients after treatment. METHODS: After eradication treatments, patients were tested with both UBT and HpSA. Cut-off values (S value over baseline at 30′) for UBT were positive (≥5%), indeterminate (3.01-4.99%), and negative (≤3%). Cut-off values (absorbance at 450 nm) for HpSA test were positive (≥0.160), indeterminate (0.159-0.140), and negative (
