- People who are above 40-year-old or who experience serious symptoms, such as repeated vomiting, weight loss, difficulty swallowing, or a low blood count, should have an upper endoscopy procedure.
- People who are below 40-year-old and who do not have serious symptoms are generally offered non-invasive testing to detect infection with H. pylori (e.g. stool or breath testing).
Your doctor may recommend other tests depending on the predominant symptom that you may have.
