What the test measures
H. pylori is a common bacterium that can live in the stomach lining and cause gastritis and stomach ulcers. The stool antigen test detects the bacterium itself, so it shows a current infection and can be used to confirm it has cleared after treatment.
The blood antibody test shows whether you have been exposed to H. pylori, but antibodies can stay in your blood for a long time after the infection has gone.
The price includes your sample collection, analysis at the Randox accredited laboratory (ISO/IEC 15189, UKAS Lab ID 9329) and a practitioner review of your result. A GP feedback report is available on request, and no GP referral is needed.
Who it is for
- You have indigestion, upper tummy pain or bloating
- You have a history of stomach ulcers
- A close family member has had stomach ulcers or stomach cancer
- You want to check that H. pylori treatment has worked
What your result means
A positive stool antigen result means H. pylori is present, and it is usually treated with a short course of antibiotics and acid-reducing medicine prescribed by your GP. A retest at least four weeks after treatment confirms it has cleared.
A positive antibody result shows past or present exposure and is not used to check whether treatment has worked.
Preparing for your test
For an accurate stool test, stop acid-reducing medicines such as omeprazole for two weeks before, and do not test within four weeks of taking antibiotics. Ask your GP before stopping any prescribed medicine.
