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...
متن کاملExperience of 13C-Urea Breath Test in Eight Children

Eight asymptomatic paediatric patients who underwent C-UBT were analyzed...
متن کاملThe 13C-urea breath test to detect Helicobacter pylori infection: a validated simple methodology with 50 mg 13C-urea.
BACKGROUND Several modifications of the 13C-urea breath test have been published. For reasons of cost efficiency and practicability, the urea dose and measurement duration should be reduced while still maintaining excellent diagnostic accuracy. AIMS To establish a validated simple protocol for the urea breath test with 50 mg 13C-urea and to compare this protocol with the conventional urea bre...
متن کاملEffect of a test meal on the intragastric distribution of urea in the 13C-urea breath test for Helicobacter pylori.
Test meals are invariably used in the 13C-urea breath test (UBT) but their effect on the intragastric distribution and gastric residence time of urea given in the test is unknown. The site of Helicobacter pylori urease measured in the test is unknown and whether the test measures total or regional gastric urease is uncertain. This study reports the results of paired UBTs with simultaneous gastr...
متن کاملThe 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...
