Helicobacter Antigen

About this test

Helicobacter pylori, H. pylori, is a bacteria which is a common cause of peptic ulcers.

This Helicobacter pylori test looks to identify Helicobacter pylori antigens, substances that trigger the immune system to fight infection, are present in the gastrointestinal (GI) system.

Symptoms that could indicate the presence of a peptic ulcer are indigestion, abdominal pain, a full or bloated feeling, nausea, frequent belching, or vomiting.

A Helicobacter pylori test also might be ordered after apersoncompletes a course of antibiotics for Helicobacter pylori to determine whether it eradicated the infection.

Helicobacter pylori testing has become a key step in the management of gastric symptoms as it is a cofactor for the majority of gastric and duodenal ulcers (70 - 75%). Eradication of Helicobacter pylori is by a short course of medication which can lead to rapid relief of symptoms and promotion of ulcer healing in many cases. Successful eradication reduces ulcer recurrence to less than 15%.

If you are taking a proton-pump inhibitor (e.g. esomeprazole, omeprazole, lansoprazole) then you should stop taking it for two weeks prior to this test.

Who is this test for?

This test is ideal for individuals who have symptoms of an ulcer and wish to check whether that is due to an infection by the h. pylori bacteria. It is also useful for people who have been treated for h.pylori and wish to confirm that the bacteria have been eradicated.
