摘要: 目的 应用全自动微粒子发光免疫分析仪(i2000)进行梅毒筛查,并通过梅毒螺旋体明胶凝集试验(Treponema pallidum particle agglutination assay,TPPA)进行确证,对采用化学发光微粒子免疫检测法(chemiluminescent microparticle immunoassay,CLIA)法筛查梅毒的结果进行分析。方法 36 000例标本均经过CLIA检测,以S/CO值大于1.0为阳性,阳性者进行TPPA确证,计算CLIA方法的检测敏感度、特异度、阳性预测值和阴性预测值。结果 以TPPA作为参考标准,CLIA的敏感度、特异度、阳性预测值和阴性预测值分别为100%、99.7%、68.3%和100%,当S/CO值为1.08时,Youden指数最大,敏感度为100%,特异度94.8%。结论 CLIA法是进行梅毒螺旋体感染初筛的可靠方法。

Abstract: Objective Compared automated chemiluminescent microparticle immunoassay (CLIA) with conventional methods to analyze the results of CLIA for the screening of syhilis.Methods 36 000 serum samples were tested by CLIA for screening of syphilis, and the positive samples would be subjected to TPPA for furhter confirmation. Then the sensibility, specificity, positive prediction value and negative prediction value were calculated. Results The sensitivity and specificity of CLIA were 100% and 99.7%, respectively. When the value of S/CO value was 1.08, the Youden index reached maximum, the sensitivity and specificity of CLIA were 100% and 94.8%, respectively. Conclusion CLIA is suggested as a screening test for the diagnosis of syphilis.
