The Helicobacter pylori test is a medical examination used to detect the presence of the Helicobacter pylori bacteria in the stomach. This bacterium is known to cause various gastrointestinal issues, including ulcers and gastritis. The test can be performed through different methods, such as blood tests, breath tests, or stool tests, each providing information about the infection. If the test is positive, treatment typically involves a combination of antibiotics and acid-reducing medications to eliminate the bacteria and promote healing. Regular testing may be recommended to ensure the infection has been successfully treated and to monitor any potential recurrence.
