03/30/2002 - "pylori infection pre-treatment was based on rapid urease test, histology and breath test, whereas 13C-urea breath test was considered the post-treatment gold standard. "

10/28/2023 - "Positive results were confirmed by a rapid urease test and histopathological examination, with the type of gastritis established according to the Sydney System. "
04/01/2001 - "According to serology, histology, rapid urease, and PCR, positive results were respectively found in 56%, 86%, 64%, and 85% of dyspeptic patients, primarily with gastritis. "
05/28/2015 - "pylori-infected chronic gastritis by electronic endoscopy and rapid urease testing from December 2012 to October 2013 were enrolled in this study. "
01/01/2023 - "Although the patient did not have autoimmune gastritis or decreased gastric acid secretion, it is presumed that oral commensal bacteria showing urease activity inhabited the stomach, resulting in the persistently positive UBT results. "
01/01/2022 - "The urease level of acute and chronic gastritis positive patients were higher than negative patients (p = 0.001, r = 0.353; p <0.0001, r = 0.433, respectively). "

07/01/2014 - "In conclusion, the present study illustrated strong antagonism of urease activity and thus validated scientifically the traditional use of the plant in the treatment of ulcers."
03/01/2010 - "Ninety-one non-ulcer dyspeptic patients infected with Helicobacter pylori as diagnosed by both histology and a rapid urease test were included in this study. "
10/01/1993 - "In this study, our objective was to determine the presence of Helicobacter pylori and other rapid urease-positive (RUP) organisms in gastric biopsies in 70 patients, 30 of whom had ulcers or erosions. "
10/01/2014 - "We report draft genome sequence of Ochrobactrum intermedium strain 229E concurrent with Helicobacter pylori in urease positive gastric biopsy of non-ulcer dyspeptic individual from Southern part of India. "
04/04/2013 - "Earlier, we reported the case of an Indian subject with non-ulcer dyspeptic symptoms whose urease positive gastric biopsy revealed the presence of Helicobacter pylori along with non-Helicobacter like bacteria, eventually cultured and identified as O. "

04/01/2003 - "Some studies show bad diagnostic results with the rapid urease test for gastrointestinal bleeding. "
01/01/2022 - "Thus, the rapid urease test plays a significantly higher role than the platelet-spleen ratio as a risk factor for bleeding (p-value = 0.001). "
03/01/2010 - "Gastroendoscopy was done to find the bleeding focus and for further evaluation including rapid urease test and mucosal biopsy. "
12/01/2005 - "Acute-GI bleeding did not decrease the sensitivity of rapid urease testing, unless the effect lasts more than 1 month. "
07/01/2002 - "False-negative rapid urease test in acute upper GI bleeding: is human plasma alone responsible?"

12/01/1996 - "To evaluate the sensitivity and specificity of a whole blood antibody test (Helisal Rapid Blood test) for the detection of Helicobacter pylori using endoscopic diagnostic criteria of histology and urease tests as the "gold standard." A prospective trial of Helisal Rapid Blood (HRB) test was carried out in patients undergoing investigations for dyspepsia that included endoscopic biopsy for rapid urease test, microbiological culture, and histology. "
08/01/2007 - "The objective of this study was to compare predictive results classifying people with organic dyspepsia with Helicobacter pylori testing (rapid urease test), a scoring system based on patients' symptoms (derived using logistic regression), classification and regression trees (CART) and the most common ANN approach used in medicine: a feed-forward multilayer perceptron (MLP) trained by back-propagation. "
04/01/1998 - "Two hundred and seventy-four patients with symptoms of dyspepsia, normal upper GI endoscopy and a positive urease test were included in the study. "
06/01/1996 - "In an open, randomized, three-centre study 120 patients (69 men, mean age 47 years, caucasians 74%) with symptoms of dyspepsia had normal gastroscopic examination and a positive urease test. "
