To Request On EPIC

For electronic requesting using EPIC (RDUH ONLY):

Search for: ‘Helicobacter pylori antigen screen (stool)‘ or test code ‘LAB397

Special Instructions

Please ensure that stool sample pots are filled between 1/3 to 1/2 full (a minimum of a pea sized amount of stool is required.) This is sufficient sample volume for all stool tests. Under-filling or over-filling stool sample pots may lead to samples being unsuitable for analysis.

If sample was taken within 4 weeks of completion of antibiotics or PPI, this can lead to a false negative result.

Do not perform test of cure, unless exclusions as per NICE guidance (Quick Reference Guide for Primary Care). If test of cure required, ensure at least 4 weeks (ideally 8 weeks) following completion of therapy.
