Clinical and Interpretive
Gastric antral biopsies can be tested for urease activity with the CLOTEST to determine whether Helicobacter pylori bacteria are present. The sensitivity of biopsy urease tests is approximately 90-95% and the specificity is 95-100%.
Antisecretory therapy may diminish numbers of bacteria and cause false negative urease tests.
