Helicobacter Pylori Testing

Helicobacter pylori is a type of bacteria that is known to be a major cause of peptic ulcer disease. H. pylori testing detects an infection of the gastrointestinal (GI) tract caused by the bacteria.

The testing result should be negative.

A positive H. pylori stool antigen, breath test, or biopsy indicates that a person’s gastrointestinal pain is likely caused by a peptic ulcer due to these bacteria.

A positive blood test for H. pylori antibody may indicate a current or previous infection. A different test for H. pylori such as the breath test may need to be done as follow up to determine whether the infection is a current one.

A negative test result means that it is unlikely that the individual has an H. pylori infection and their signs and symptoms may be due to another cause. However, if symptoms persist, additional testing may be done, including the more invasive tissue biopsy, to more conclusively rule out infection.
