Notification of change in service for the diagnosis of H Pylori Infections

The laboratories at HEFT are changing the way we diagnose H. pylori infections. Urease breath tests (UBT) and blood tests (helicobacter serology) will no longer be available from our laboratories with immediate effect. These tests are being replaced with a Stool Antigen Test (SAT).

Guidance released in 2012 on the management of H. pylori (Management of Helicobacter pylori infection—the Maastricht IV/ Florence Consensus Report) indicates that the SAT is equivalent to UBT in terms of diagnostic performance and does not require a hospital appointment like UBT. Helicobacter serology is also not recommended by updated PHE guidelines for most patients (PHE H. pylori guideline).

The stool antigen is reliable for both diagnosis and post eradication testing, provided the patient has avoided PPIs for 2 weeks and antibiotics for 4 weeks prior to sample collection.

A stool sample is required and samples must arrive in the laboratory within 48 hours of collection. Patients should be advised to bring the properly labelled stool sample in a blue topped sample pot (picture below) to the GP surgery or laboratory reception as soon as possible after collection, ideally same day or next morning.
