Eight commercial enzyme-linked immunosorbent assays (ELISAs) were used to
test sera taken from 102 patients in whom Helicobacter pylori infection
status had been determined by means of biopsy culture, PCR, histology, and
urease production and by 13C urea breath test. By those means, 61 patients
had been found to be infected. Assays were compared by receiver operating
characteristic analysis. Sensitivities ranged from 86 to 98%; specificities
ranged from 83 to 98%. In a group consisting of the assays by
Bio-Whittaker, Meddens Biotech, Orion (Pyloriset EIA G, new version), and
Enteric Products, Inc. (HM Cap), differences in performance were not
statistically significant. Sensitivities in this group ranged from 93 to
98%; specificities ranged from 95 to 98%. Assays from this group may be
useful in addition to biopsy-based methods in diagnosing H. pylori
infection.
