Helicobacter pylori Tests - Results
About this test
Helicobacter pylori tests are used to detect a Helicobacter pylori (H. pylori) infection in the stomach and upper part of the small intestine (duodenum).
Results from the urea breath test or a stool antigen test are usually available within a few hours. Results from a blood antibody test are usually available within 24 hours. Results from biopsy samples obtained by endoscopy are usually available within 48 hours. Results from a biopsy sample that is cultured can take up to 10 days.
