三种常用幽门螺杆菌检测方法的评价

目的:对14C尿素呼气试验(14C-UBT)、快速尿素酶试验(RUT)、血清学检测抗幽门螺杆菌抗体(IgG)试验(HpAb-IgG)3种临床常用幽门螺杆菌(HP)检测方法进行回顾性评价。方法:对73例经内镜确诊的活动性消化性溃疡病病例进行14C-UBT、RUT、HpAb-IgG3项检测,采用四格表卡方检验对3项检测结果的敏感性、特异性及准确性进行统计学比较。结果:HpAb-IgG的敏感性显著高于14C-UBT(χ2=12.07,P<0.01)和RUT(χ2=21.06,P<0.01);HpAb-IgG的特异性显著低于14C-UBT(χ2=9.14,P<0.01)和RUT(χ2=9.14,P<0.01);HpAb-IgG的准确性高于RUT(χ2=4.96,P<0.05)。结论:HpAb-IgG检测结果中可能有部分为假阳性结果,14C-UBT和RUT检测结果中可能存在部分假阴性结果。

Evaluation of three diagnostic tests for helicobacter pylori infection

Objective To explore the accuracy of 14C urea breath test(14C UBT),rapid urease test(RUT) and serological test for helicobacter pylori antibody(HpAb IgG) in helicobacter pylori(HP) infectionMethods Seventy three active peptic ulcer patients were determined by 14C UBT,RUT and HpAb IgGThe sensitivity,the specificity and the accuracy of the three tests were analyzed with Chi square testResults The sensitivity of HpAb IgG was statistically and significantly higher than that of 14C UBT(χ2=1207,P< 001) and R...
