摘要 目的比较免核酸提取法与煮沸裂解法对HBV—DNA提取后荧光定量PCR检测结果的影响。方法用两种前处理方法不同的试剂盒检测7.0×102~7.0×107IU/ml的HBV—DNA阳性标准品和84例临床小三阳患者血清,对结果进行重复性、相关性分析。并计算两种方法对低浓度HBV—DNA值的阳性检出率。结果阳性标准品HBV—DNA浓度大于103IU/ml样本的均值两种方法比较,相关性良好(线性相关,r=0.993),CV比较发现,免核酸提取比煮沸裂解的CV要小。临床小三阳患者84例HBV—DNA浓度在1酽~103IU/ml的标本,免核酸提取法阳性检出率为25%高于煮沸裂解法的11.9%(P=0.015)。结论免核酸提取法操作简单,结果稳定可靠,线性范围宽,有益于乙肝病毒感染窗口期的早期诊断。
