- Ordering Info
Negative antibody tests indicate absence of current and potentially past infection. Antibody tests are not recommended after treatment of H. pylori. Stool antigen and urea breath tests are effective in identifying present infection.
|H. pylori Ab (IgG)||Negative|
|H. pylori Ab (IgA)||Negative|
|H. pylori Ab (IgM)||Negative|
Colonization with H. pylori is associated with increased risk of patients developing gastritis, peptic ulcer disease, and gastric adenocarcinoma. Serologic testing is recommended only for symptomatic patients. Antibodies IgG, IgA, and IgM provide higher sensitivity than any single antibody test alone.
