Could the [14C]urea breath test be proposed as a 'gold standard' for detection of Helicobacter pylori infection ?

Background: The urea breath test (UBT) with a microdose of [14C] is a non-invasive and simple method for the assessment of gastric infection by Helicobacter pylori. The aim of this study was to compare the [14C]UBT with invasive methods widely used for assessment of H. pylori gastric infection, including histology with hematoxylin-eosin staining, the gastric smear technique using Giemsa staining, and the biopsy urease test.

[An Elisa stool test to detect Helicobacter pylori infection].

Aim: To report the use of an immunoassay test, that detects antigens of Helicobacter pylori in stools.

Material And Methods: One hundred and four patients that required an upper gastrointestinal endoscopy were studied.
