The detection of H. pylori stool antigen is intended to aid in the diagnosis of H. pylori infection. This can also be used to demonstrate loss of H. pylori following treatment, however it is recommended that this is done at least four weeks following completion of therapy.
H. pylori has been established as an etiologic agent in chronic gastritis and peptic ulcer disease, and has been associated with mucosa-associated lymphoid tissue lymphoma and gastric adenocarcinoma.
