Sometimes the presence of this bacterium can cause gastritis and ulcers in the stomach or duodenum. The most common symptoms of these conditions are: burning or pain in the upper abdomen, especially between meals when the stomach is empty, nausea and a sense of fullness, reflux, loss of appetite and weight loss. On the long-term the Helicobacter pylori infection is associated with an increased risk of gastric cancer.


HELICOBACTER PYLORI ANTIGEN TEST is intended for anyone who wants to identify the presence of the bacterium in the body.

  • 1 test cassette
  • 1 vial with collection stick and dropper containing the diluent
  • 1 paper sheet for the collection of the sample
  • instructions for use


  1. Collect the sample using the special collection sheet;
  2. Unscrew the cap of the vial, plunge the withdrawal stick in 3 different points of the sample and screw the cap back on;
  3. Break the end of the cap, freeing the dropper part, and dispense 3 drops of the diluted sample into the well (S) indicated on the cassette;
  4. Wait 10 minutes before reading the result.


Negative no H. pylori antigens have been detected in the sample or their concentration is below the 10 ng/mL cut-off.
Positive Helicobacter pylori antigens have been detected in the sample, it is necessary to check with a specialist, as a possible bacterial infection is ongoing.

The test has been carried out correctly when the instructions for use are followed. It includes the reading time and the interpretation of the results shown at the "RESULTS INTERPRETATION" section of the instructions for use.

A colored line will appear at the control region (C) on the test device, showing that the test performed correctly. The absence of the colored line suggests to repeat the test with a new device and a new sample.

The color and intensity of the lines do not affect the interpretation of the result. The test has to be considered positive regardless of the color intensity of the test line (T).
