摘要 目的探讨用不同方法检测抗核小体抗体(AnuA),评价方法的分析性能、相关性及对系统性红斑狼疮(sgstem—iclupus erythematosus,SLE)的诊断价值。方法用化学发光免疫分析法(CLIA)、间接免疫荧光法(IIF)、酶联免疫斑点法(ELISPOT)和酶联免疫吸附试验(ELISA)检测AnuA,四种方法分别检测200例SLE组患者,200例疾病对照组患者和100名健康人对照组血清抗核小体抗体。结果CLIA法灵敏度最高,其次是ELISA、ELISPOT、IIF。ELISPOT法特异性最高。CLIA法与IIF法,ELISPOT法之间相关性X2检验差异有统计学意义(P〈0.01)。CLIA法与ELISA法高度一致(Kappa值0.909)。结论本研究提示ELISA法与ELISPOT法联合是临床实验室检测抗核小体抗体的最佳方案。
