Stool antigen assay (HpSA) is less reliable than urea breath test for post-treatment diagnosis of Helicobacter pylori infection

Limitations of C-urea Breath Test (ubt) and Stool Antigen Test (sat) in Diagnosis of Helicobacter Pylori (hp) Infections

Helicobacter pylori (HP)(1) management (including diagnosis and therapy) has been exhaustively reviewed in several reports. These reports are unanimous in that several clinical conditions seriously hamper the diagnostic value of two HP tests: 13 C-Urea Breath Test (UBT) and Stool Antigen test (SAT), because of the false-negative results frequently (up to 40%) obtained in these conditions. Basic...

Evaluation of [13C]urea breath test and Helicobacter pylori stool antigen test for diagnosis of H. pylori infection in children from a developing country.

The [(13)C]urea breath test ((13)C-UBT) and Helicobacter pylori stool antigen test (HpSA) for the diagnosis of H. pylori infection in children were validated. The sensitivity, specificity, and positive and negative predictive values were 93.8, 99.1, 97.8, and 98.0%, respectively, for the (13)C-UBT and 96.9, 100, 100, and 98.0%, respectively, for HpSA. Both tests are appropriate for diagnosing H...

Determination of Helicobacter pylori Antigen in Stool Samples and Comparison with Rapid Urease Test in Patients Suspected of Helicobacter Infection

Background and Aims: Helicobacter pylori (H. Pylori) is the microorganism that infects nearly half of word's population. There are several invasive and non-invasive methods for diagnosis of infection. The main objective of this study was to evaluate antigen of H. Pylori in feces with H. pylori stool antigen (HpSA) test and comparison with rapid urease test (RUT) in the patients suspected to be ...

Diagnostic values of Helicobacter pylori diagnostic tests: stool antigen test, urea breath test, rapid urease test, serology and histology*

BACKGROUND The purpose of this study is to compare validity of 5 diagnostic tests of helicobacter pylori with each other: stool antigen test, urea breath test (UBT), rapid urease test (RUT), serology and histology. METHODS A total of 94 patients who had indication of endoscopy entered the study. All of the 5 tests were performed for each patient. When the results of at least 2 tests were posi...
