摘要 目的 对目前国内各种广泛应用于婴、幼儿的CMV实验室检测方法进行初步评价。方法 本研究建立了应用间接荧光免疫法测定CMV细胞核抗早期抗原抗体 (PENA)的新方法 ,同时进行PCR检测和ELISA检测IgM、IgA、IgG实验 ,对 4 91例临床可疑为CMV感染的患儿进行检测 ,同时进行PCR方法及ELISA -IgM、IgA、IgG方法的检测 ,观察结果 ,并与尿中寻找CMV包涵体方法结果相比较。结果 PENA( 1/2 0 )阳性率 5 4 99% ,PENA( 1/10 0 )阳性率 2 1 70 % ,PCR方法的阳性率 5 5 80 % ,ELISA -IgM阳性率 8 76 % ,ELISA -IgA阳性率 5 5 0 % ,ELISA -IgG阳性率 6 8 4 3%。结论 PENA方法可以特异的检测出病人血清中的抗病毒早期抗原抗体的存在 ,并具有敏感、特异、简便的特点 ,是一种实验室检测CMV的新方法 ,可作为临床检测CMV感染的补充方法 。
