S. Kamiya et al., EVALUATION OF RAPID UREASE TEST FOR DETECTION OF HELICOBACTER-PYLORI IN GASTRIC BIOPSY SPECIMENS, European journal of epidemiology, 9(4), 1993, pp. 450-452
Using 80 gastric biopsy specimens from patients with various gastroduo
denal diseases, the isolation rate of H. pylori and urease activity of
the biopsy specimens were examined. The sensitivity and specificity o
f the rapid urease test was 84.6% and 75.9%, respectively, for the. cu
ltivation of H. pylori. The mean number of H. pylori detected in ureas
e-positive and negative biopsy specimens was 10(6.1 +/- 0.9) and 10(4.
5 +/- 1.2) Cfu/g specimens, respectively.
