General Information
This test is used to diagnose infection due to Helicobacter pylori.
A positive H. pylori test indicates that your gastrointestinal pain may be due to a peptic ulcer caused by this bacteria. Antibiotic treatment will erradicate the H.pylori infection and the associated symptoms will be alleviated.
The H.pylori Stool antigen is reliable both in the diagnostic and post eradication settings provided the patient has avoided PPI’s for 2 weeks and antibiotics for 4 weeks prior to sample collection as they may interfere with this assay.
The Urea breath test was always the gold standard but a lack of standardisation and quality control means it is not always a reliable test.
