Can urea breath test (UBT) replace rapid urea test (RUT)?

Polish Journal of Surgery, 2018
Background: Helicobacter pylori (Hp) is classified by the International Agency for Research on Cancer (IARC) as a Group 1 carcinogen. Its influence on the carcinogenesis of gastric cancer has been confirmed in many researches. The conclusion is obvious- early detection and eradication of Hp can prevent the development of the disease.

Urea Breath Test

2016
The urea breath test (UBT) is a noninvasive, simple, and safe test which provides excellent accuracy both for the initial diagnosis of Helicobacter pylori infection and for the confirmation of its eradication after treatment (high sensitivity, 90–100 % and specificity, 90–100 %).

CAMPYLOBACTER PYLORI DETECTED NONINVASIVELY BY THE 13C-UREA BREATH TEST

The Lancet, 1987
The high endogenous urease activity of Campylobacter pylori was exploited in a non-invasive test for the presence of this organism in the stomach. When 13C-urea was administered orally after a test meal, urea-derived 13CO2 appeared in the respiratory CO2 of infected individuals at a constant rate for greater than 100 min.

Helicobacter pylori “Test‐and‐Treat” strategy with urea breath test: A cost‐effective strategy for the management of dyspepsia and the prevention of ulcer and gastric cancer in Spain—Results of the Hp‐Breath initiative

Helicobacter, 2020
Data from clinical trials comparing Helicobacter pylori (H. pylori) management strategies in patients with dyspepsia are limited. Cost‐effectiveness simulation models might help to identify the optimal strategy.

Urea Breath Test and Rapid Urease Test

2016
The urea breath test (UBT) and the rapid urease test (RUT) are the most commonly used diagnostic methods for H. pylori infection and rely on detecting the presence of urease produced by H. pylori. The sensitivity of the UBT is excellent (often exceeding 95 %).

13C-Urea Breath Test Values and Helicobacter pylori Eradication

Digestive Diseases and Sciences, 2007
Delta over baseline (DOB) values of 13C-urea breath test (UBT) have been shown to be predictive of H. pylori eradication following therapy. This was a post hoc analysis of a large, double-blind, randomized trial. Consecutive patients with a positive UBT underwent upper endoscopy. H. pylori strains were tested for clarithromycin resistance. All patients

Gastroscopic Real-Time¹³C-Urea Breath Test

Endoscopy, 2005
Biopsy-based Helicobacter urease testing (HUT) may constitute a hazard in patients with bleeding disorders, those receiving anticoagulant therapy, and those with communicable diseases. In addition, definitive test results may not immediately be available. The aim of this study was to investigate the feasibility of breath testing for H.

[14C]urea breath test for diagnosis ofHelicobacter pylori

Digestive Diseases and Sciences, 1990
H. pylori is a potent urease producer, a characteristic that has been exploited in the development of the [14C]- and [13C]urea breath tests. The prevalence of H. pylori infection also is known to increase with advancing age; however, the individual patient's age has not routinely been considered when interpreting urea breath test results.
