摘要 目的评价ELISA、绿蝇短膜虫间接荧光法(CLIFT)和免疫印迹法(IBT)检测抗双链DNA(dsDNA)抗体的结果差异。方法用三种方法分别检测85例SLE患者、60例非SLE的自身免疫病患者和200例体检健康者血清抗dsDNA抗体,以临床诊断为金标准,评价各法对SLE的诊断性能。结果 ELISA、CLIFT和IBT 3种方法诊断SLE的敏感性分别为76.47%、68.24%、61.18%,特异性分别为94.62%、98.85%、97.69%;Youden指数分别为0.710 9、0.670 9和0.588 7,差异无统计学意义(u=0.53、1.70和1.03,P〉0.05)。3种方法 kappa值为0.65~0.71。结论 3种方法结果一致性较好,CLIFT法有较高的特异性而ELISA法有较高的敏感性。单独使用一种方法易漏检,可两法或三法联合应用。
