2、200全自动免疫分析仪(简称BioPlex。2200)检测抗环瓜氨酸肽(CCP)抗体的分析性能和临床应用价值。方法采用BioPlex2200检测65例类风湿关节炎(RA)患者、46例非RA患者(自身免疫疾病31例、骨关节炎15例)及20名表面健康者血清抗CCP抗体,评价其分析性能和初步临床应用价值,并与Roche检测系统进行一致性比较。结果高、中、低浓度混合血清的批内精密度分别为2.4%、3.3%、4.4%;天问精密度分别为4.5%、3.5%、5.6%。经多项式回归分析,BioPlex2200在0.
3、5~294.6U/mL范围内呈线性。BioPlex2200与Roche检测系统结果的一致性较好(kappa值为0.873)。受试者工作特征(ROC)曲线显示抗CCP抗体诊断RA的最佳诊断Cut—of值为2.3U/mL,诊断灵敏度和特异性分别为80.O%和98.5%。结论BioPlex2200检测抗CCP抗体的分析性能较好,能够适用于临床对于RA的诊断和疗效评估。关键词:抗环瓜氨酸肽抗体;类风湿关节炎;精密度;线性;受试者工作特征曲线Theanalyticalperformanceevaluation
