|Causal associations||Appropriate Tests|
Endoscopy with gastric or duodenal biopsy (special stains) to identify Helicobacter pylori; the urease test can be used for rapid identification of infection, but is less sensitive than histology.
Culture for sensitivity testing if recurrent or refractory disease.
Molecular genetics - microbial testing is available in some laboratories.
H. pylori antibodies provide evidence of infection, but are of limited value as a positive result does not distinguish past from current infection.
Antibody levels decline slowly after therapy.
Urease breath test can be used to identify continuing infection.
