The Helicobacter Pylori Infection in Upper Aerodigetive Tract Mucosal Disease by Urea Breath Test(UBT)

Urea breath tests in the management of Helicobacter pylori infection.

The 13/14C-Urea breath test (UBT) is based on the simple principle that a solution of isotopically labelled urea will be rapidly hydrolysed by the abundantly expressed urease of H pylori. The released 13/14CO2 is absorbed across the mucus layer to the gastric mucosa and hence, via the systemic circulation, excreted in the expired breath. Distribution of urea throughout the stomach prevents samp...

The urea breath test for Helicobacter pylori.

Helicobacter pylori infection in various groups of patients studied, estimated by 14C-urea breath test.

The aim of this study was the detection of helicobacter pylori (HP) infection and estimation of the clinical validity and the accuracy of the 14C-urea breath test in the groups of patients studied. A total of 248 patients with gastric diseases were examined. There were 38 patients with gastric ulcer, 41 with duodenal ulcer, 43 with gastroduodenitis erosiva, 26 with hiatus hernia, 36 with gastri...

The 13C urea breath test in the diagnosis of Helicobacter pylori infection.

The urea breath test (UBT) is one of the most important non-invasive methods for detecting Helicobacter pylori infection. The test exploits the hydrolysis of orally administered urea by the enzyme urease, which H pylori produces in large quantities. Urea is hydrolysed to ammonia and carbon dioxide, which diffuses into the blood and is excreted by the lungs. Isotopically labelled CO2 can be dete...

The C urea breath test in the diagnosis of Helicobacter pylori infection

The urea breath test (UBT) is one of the most important non-invasive methods for detecting Helicobacter pylori infection. The test exploits the hydrolysis of orally administered urea by the enzyme urease, which H pylori produces in large quantities. Urea is hydrolysed to ammonia and carbon dioxide, which diVuses into the blood and is excreted by the lungs. Isotopically labelled CO2 can be detec...
