Helicobacter Pylori Test

HELICOBACTER PYLORI

Helicobacter pylori is a bacterium, whose ideal habitat is the human gastric mucosa, causing an often asymptomatic infection of the gastrointestinal tract.

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.

WHO IS THIS TEST FOR?

HELICOBACTER PYLORI TEST is useful for a first screening of an ongoing or a past infection of H. pylori.

This bacterium chronically affects about half of the world’s population and plays an important role in the pathogenesis of chronic gastritis, peptic ulcer, gastric cancer, and mucosal-associated lymphoid tissue lymphoma.

TECH SPECS

HELICOBACTER PYLORI TEST is an immunochromatographic device that detects the presence of anti-Helicobater pylori IgG antibodies in blood samples.

Specificity 84.2%
Sensitivity 95.8%
Accuracy 87%

CONTENT

  • 1 test cassette
  • 1 vial with dropper containing the diluent
  • 2 sterile lancets
  • 1 pipette for blood sampling
  • 1 cleanser gauze
  • instructions for use

USE PROCEDURE

  1. Draw a blood sample by using the sterile lancet provided;
  2. Collect the sample indicated with the black line by using the capillary pipette provided;
  3. Deposit the collected specimen into the sample well (S) indicated on the test cassette;
  4. Add 2 drops of the diluent and wait 5 minutes before reading the result.

RESULTS INTERPRETATION

Negative no IgG antibodies against Helicobacter pylori have been detected in the sample or their concentration is below the cut-off of 15 AU/mL.
Positive IgG antibodies against Helicobacter pylori have been identified in the sample, it is necessary to check a possible exposure to the bacterium with a specialist.

F.A.Q.

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).
