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.
使用8种商用酶联免疫吸附测定法(ELISA)检测了102例患者的血清,这些患者的幽门螺杆菌感染状况已通过活检培养、聚合酶链反应(PCR)、组织学、尿素酶产生情况以及13C尿素呼气试验确定。通过这些方法,发现61例患者受到感染。通过接受者操作特征分析对各测定法进行了比较。敏感性范围为86%至98%;特异性范围为83%至98%。在由Bio-Whittaker、Meddens Biotech、Orion(Pyloriset EIA G,新版本)和Enteric Products公司(HM Cap)的测定法组成的一组中,性能差异无统计学意义。该组中的敏感性范围为93%至98%;特异性范围为95%至98%。除基于活检的方法外,该组中的测定法可能有助于诊断幽门螺杆菌感染。
