If you are showing symptoms of H. pylori or have a strong family history of stomach cancer the physician can diagnose the infection with various test methods. Medicines such as nonsteroidal anti-inflammatory drugs (NSAIDs) can also cause damage to the stomach lining therefore its important to identify what is causing the symptoms in order to choose the correct treatment plan. H. pylori can be identified with blood, breath, or stool tests.

  • Blood test: A little blood is drawn from the arm; the sample is then sent to a laboratory for analysis.
  • Stool test: A container is given in which a stool sample is provided by the patient, this sample is then sent to a laboratory for analysis.
  • Breath test: The patient is requested to drink a pre-prepared substance containing urea, if H. pylori is present the enzyme in the fluid breaks down H. pylori releasing carbon dioxide, which is then detected by the special breathalyzer.

To investigate the ulcers more closely the physician may also use the following methods:

  • Endoscopy: A small tube with a camera at the end is inserted through the mouth and down the throat into the upper small intestine.
  • Upper GI test: The patient is requested to drink a fluid called barium; an X-ray is then carried out. The fluid coats the throat and stomach which makes them stand out in the X-ray allowing a thorough examination.
  • Computed tomography (CT) scan: Is an advanced X-ray that makes detailed pictures of the inside of the body.
  • Biopsy: A small piece if tissue is taken from the stomach lining in order to look for signs of cancer. This is often conducted during an endoscopy.
