A positive urease test indicates the presence of H. pylori infection. Because H. pylori is the only bacterium in the human stomach that can produce large amounts of urease, H. pylori infection can be diagnosed by testing for urease.

Patients who are positive for urease are advised to cooperate with their doctors for timely treatment. If H. pylori infection is not treated actively, it may develop into peptic ulcer or stomach cancer.
