摘要 目的探讨血清糖链抗原125(CA125)临床测定结果在3种化学发光检测系统间的可比性,并确定其相关性。方法选取100例患者血清,分别使用化学发光酶免疫分析法(CLEIA)、电化学发光免疫检测法(ECLIA)和直接发光免疫分析法(CLIA)进行CA125检测,对各组数据进行相关性分析与中位数比较。结果 3组结果中任意两组之间均存在相关性,对3组样本间中位数进行比较,结果显示3组之间差异有统计学意义(P<0.05),CLE-IA组显著高于ECLIA组与CLIA组,差异有统计学意义(P<0.05),而ECLIA组与CLIA组之间差异无统计学意义(P>0.05);以大于或等于35U/mL即判断为阳性,CLEIA组阳性率为76%(76/100),ECLIA组阳性率为58%(58/100),CLIA组阳性率为53%(53/100),CLEIA组阳性率显著高于ECLIA组与CLIA组,差异有统计学意义,而ECLIA组CLIA组阳性率差异无统计学意义。结论建议对CA125建立标准化的参考系统,现有的检测系统应与标准化的参考系统进行比对。
