Test Details


  • Anti-H pylori, IgG
  • Anti-Helicobacter pylori Antibodies

Test Includes

Qualitative result for IgG


The qualitative determination of IgG antibodies to Helicobacter pylori (H. pylori) in human serum from symptomatic adults as an aid in the diagnosis of H. pylori infection.


Assay results should be utilized in conjunction with other clinical and laboratory data to assist the clinician in making individual patient management decisions. Heterophilic antibodies in human serum can react with reagent immunoglobulins or other reagent material, interfering with in vitro immunoassays.

This assay has not been evaluated in a pediatric population.

This assay should be used only to evaluate patients with clinical signs and symptoms suggestive of gastrointestinal disease and is not intended for use with asymptomatic patients.

A positive test result does not allow one to distinguish between active infection and colonization by H. pylori. A positive test only indicates the presence of IgG antibody to H. pylori and does not necessarily indicate that gastrointestinal disease is present.

A negative test indicates that IgG antibody to H. pylori is not present or is at a level that cannot be detected by the assay.
