Follow-up test for H. pylori infection

For some people who have taken medicine to treat a Helicobacter pylori (H. pylori) infection, a follow-up test may be needed to make sure the infection is cured. The American College of Gastroenterology recommends a follow-up test to check for H. pylori infection whenever:1

  • A peptic ulcer is caused by H. pylori infection.
  • Stomach (gastric) mucosa-associated lymphoid tissue (MALT) lymphoma is caused by H. pylori infection.
  • Upset stomach (dyspepsia) symptoms are present even after H. pylori infection was tested for and treated.
  • Resection of early stomach (gastric) cancer has been done.
