Introduction

Helicobacter pylori is a type of bacteria that causes infection in the stomach. It is a common cause of peptic ulcers and can lead to chronic gastritis and gastric cancer if left untreated. A Helicobacter pylori test helps to diagnose this bacterial infection, assess its impact, and guide treatment decisions.

Uses of Helicobacter pylori Test

The Helicobacter pylori test is essential for diagnosing infections caused by H. pylori bacteria. It is primarily used to:

  • Confirm an H. pylori infection in patients with peptic ulcer symptoms.
  • Evaluate the effectiveness of treatment for H. pylori infections.
  • Screen for potential gastric cancer risks in high-risk populations.

Types of Helicobacter pylori Tests

Multiple testing methods are available, each with distinct characteristics:

1. Urea Breath Test

In this test, patients ingest urea labeled with an isotope that can be detected in the breath. The test has a sensitivity and specificity of approximately 95%.

2. Stool Antigen Test

This test detects antigens associated with H. pylori in the stool. It is non-invasive and boasts an accuracy of around 90%.

3. Blood Antibody Test

This test identifies antibodies against H. pylori in the blood. However, it is less specific and can result in false positives due to past infections.

4. Endoscopic Biopsy

An invasive method that involves direct biopsy of the gastric mucosa. It provides more accurate results but is more costly and requires sedation.

Test Procedure

The procedure varies depending on the type of test employed:

  • Urea Breath Test: The patient is instructed not to eat or drink for a certain period before the test. A baseline breath sample is taken, followed by ingestion of the urea solution.
  • Stool Antigen Test: The patient provides a stool sample, which is then analyzed in a laboratory.
  • Blood Antibody Test: A blood sample is drawn and sent for analysis.
  • Endoscopic Biopsy: Conducted in a medical facility where the patient is sedated, and a biopsy is taken for examination.
