Do you need more information

Helicobacter pylori (H. pylori) is a microorganism that colonizes the stomach in about 50% of all humans(1), leading to chronic gastritis. Among the patients colonized by H. pylori, 1-10% will develop a gastric or duodenal ulcer, and 0.3 – 3% will develop a stomach cancer(2). H. pylori is now recognized as the first microorganism involved in cancer.

BIONEXIA® H. pylori Ag test detects Helicobacter pylori antigen in human stool specimens (adult and children). It is an accurate aid for the diagnosis of active H. pylori infection for patients presenting with symptoms of gastritis and/or ulcers, and to confirm H. pylori eradication after treatment(3).

Ease of use for universal practice

A simple process for results in just 10 minutes:

1 - Collect and extract stool sample:

H. Pylory detection - Step 1

2 - Apply 4 drops of sample into the cassette sample well, and read the result between 10 and 15 minutes later:

H. Pylory detection - Step 2     H. Pylory detection - Step 3


  • Applicable for use in laboratories and for near-patient testing as part of a medical consultation

A key element of the Test-and-Treat Strategy

The test-and-treat strategy involves a non-invasive test for H. pylori and immediate treatment of the infection when positive. Within a certain population, it can avoid endoscopies and then avoid risk, cost and patient discomfort.

A test-and-treat strategy using a non-invasive test such as a stool antigen test is appropriate for uninvestigated dyspepsia in populations where the H. pylori prevalence is over 20% (3).

Using stool antigen testing with repeat testing after treatment is the most cost-effective approach(4). For every 1000 people managed under this strategy (assuming 75% prevalence), experts expect that 3.0 gastric cancers and 22.8 ulcers should be prevented(4).

Stool antigen tests have been shown to significantly lower the overall costs of screening, especially in populations with high prevalence of H. pylori(5).
