Test Utilization: Improving ordering practices for the diagnosis of Helicobacter pylori


Helicobacter pylori infects half of the world’s population and is a major gastric pathogen associated with multiple gastric illnesses, including gastritis, peptic ulcer disease, and gastric cancer. The field of H. pylori diagnostics and treatment has evolved rapidly in the past decade, leading to updated management guidelines from both the American Gastroenterology Association and American College of Gastroenterology. This lecture will discuss the tests available for H. pylori diagnostics, and outline the tests that are useful for establishing diagnosis and those that are not recommended. Additionally, the specific guidelines will be outlined for test-and-treat strategies for management of H. pylori-associated disease.
