Low dose capsule based 13c-urea breath test compared with the conventional 13c-urea breath test and invasive tests.

CONTEXT One of the limitations of 13C-urea breath test for Helicobacter pylori infection diagnosis in Brazil is the substrate acquisition in capsule presentation. OBJECTIVES The purpose of this study was to evaluate a capsule-based 13C-urea, manipulated by the Pharmacy Division, for the clinical practice. METHODS Fifty patients underwent the conventional and the capsule breath test. Samples...

An optimized 13C-urea breath test for the diagnosis of H pylori infection.

AIM To validate an optimized (13)C-urea breath test ((13)C-UBT) protocol for the diagnosis of H pylori infection that is cost-efficient and maintains excellent diagnostic accuracy. METHODS 70 healthy volunteers were tested with two simplified (13)C-UBT protocols, with test meal (Protocol 2) and without test meal (Protocol 1). Breath samples were collected at 10, 20 and 30 min after ingestion ...
