检测幽门螺杆菌粪便抗原的临床价值——附94例检测结果分析

目的 对检测幽门螺杆菌粪便抗原诊断幽门螺杆菌（Ｈｐ）感染的准确性进行临床评价。方法：采用酶联免疫分析法检测９４例因上消化道接受胃镜检查病人的幽门螺杆菌便抗原（ＨｐＳＡ），以快速尿素酶、组织学检测结果作为诊断ＨＰ的标准。结果：在快速尿素酶、组织学检查均阳性的４４例中，ＨＰＳＡＳ的阳性的有４２例，阴性的有２例；而在快速尿毒酶、组织学检查阴性的５０例中，ＨＰＳＡ检测为阴性的有４９例，阳性的有１例。ＨＰＳ

Helicobacter pylori stool antigen test: clinical evaluation of a new enzyme immunoassay

Objective: To evaluate the usefulness of helicobacter pylori (H pylori) stool antigen (HpSA) test as a predictor of H.phylori status. Methods: Stool specimens of 94 patients who had gastroscopy with biopsy at our endoscopy unit were collected.H py- loristatus was defined positive (or negative)if both histology and rapid urease test were positive (or negative). A specific enzyme-linked immunosorbent assay (ELISA)was used tO test the stools for the presence of H pylori antigen. Results: Forty-four patients were diag- nosed as H phlori positive and fifty as negative by histology and rapid urease test. The HpsA test was positive in 42 of M patients and negative in 49 of 50 patients. Sensitivity, specifity and diagnostic accuracy of HpSA were 95%(42/44), 98%(49/50)and 97%(91/94) respectively. Conclusion: HpSA is a noninvasive, simple, relible method for evaluating H.pylori status.
