A gastric juice-based PCR assay was compared with culture,
microscopy, and a rapid urease test with specimens from 114 subjects. The PCR and conventional tests were positive for 76 and 62% of the
subjects, respectively. The prevalence of gastroduodenal disease and
seropositivity for anti-Helicobacter pylori immunoglobulin G were similarly high among conventional-test-positive and
PCR-only-positive subjects compared to all-negative ones. The PCR assay
is recommended to confirm the H. pylori status of
culture-negative peptic-ulcer patients.
