Abstract
目的进行非侵入性粪便标本幽门螺杆菌抗原检测诊断儿童幽门螺杆菌(H.pylori)感染,并评价此试验方法的应用价值.方法选择有上消化道症状的48例患儿为研究对象,采用H.pylori抗原检测试剂盒,以酶联免疫分析双抗体夹心法检测粪便H.pylori抗原,并与胃粘膜活检标本快速尿素酶试验、组织学、血清学试验作对比研究.结果 4种诊断试验诊断准确率分别为:粪便抗原试验95.8%,快速尿素酶试验95.9%,组织学97.9%,血清学83.7%.粪便抗原试验的特异度和敏感度分别为100%,93.6%.结论粪便标本H.pylori抗原试验诊断儿童幽门螺杆菌感染有较高的准确率、敏感性和特异性,为新的简便易行的非侵入性方法.
