Diagnosing H. Pylori Infection: Peptic Ulcer

Several methods may be used to diagnose H. pylori infection. Blood, breath and stomach tissue tests may be performed to detect the presence of H. pylori

Blood tests: Blood tests are most common. They detect antibodies to H. pylori bacteria. Blood is taken at the doctor's office through a finger stick

• Breath tests: A breath test can determine if you are infected with H. pylori. In this test, you drink a harmless liquid and in less than 1 hour, a sample of your breath is tested for H. pylori.
• Endoscopy: Your doctor may decide to perform an endoscopy. This is a test in which a small tube with a camera inside is inserted through the mouth and into the stomach to look for ulcers. During the endoscopy, small samples of the stomach lining can be obtained and tested for H. pylori.
