Diagnostic test for the detection of H. pylori - Diasorin


Diagnosis, eradication and monitoring
of H. pylori infection

Helicobacter pylori (H. pylori) is a bacterium living in the mucus of the human digestive tract and is present in half of the world population (10.3748/wjg.14.3149). H. pylori infection is a major risk factor for gastric adenocarcinoma. Diagnosis of infection can be achieved by non-invasive methods, such as detection of H. pylori antigens in stool samples. This kind of assay provides a simple alternative to the urea breath test and is an aid in diagnosis of suspected infection and to measure a patient’s post-therapy response. 

The “Houston Consensus Conference on Testing for Helicobacter pylori Infection in the United States” ( states that all patient receiving treatment for H. pylori should receive post-treatment confirmation of eradication. The LIAISON® Meridian H. pylori SA test is one of the tests recommended for eradication.

How it works

LIAISON® H. pylori Diagnostic Solution is intended for the qualitative determination of H. pylori.
