摘要 目的通过对某国产定性试剂检测HBsAg弱反应结果的分析,探讨HBsAg检测的影响因素及"灰区"的设定。方法用某国产ELISA试剂对140 709份血清样本进行HBVM定性检测,对HBsAg弱反应结果样本再用Abbott公司试剂定量检测HBVM。对定性和定量结果不相符的样本用另一种定性试剂验证。对部分弱反应定性结果样本进行HBV DNA检测,同时采用定性和定量两种试剂测定一系列HBsAg定值参比血清,比较其灵敏度。结果140 709份样本中HBsAg可疑者174份(0.124%),弱阳性者126份(0.089%)。对其中49份可疑样本和41份弱阳性样本进行定量检测,结果阳性者分别为39份和32份,符合率分别为79.59%和78.05%。17份HBsAg定性弱反应性而定量阴性的样本经另一种定性试剂验证,结果2份为弱反应性,其中1份样本为HBV DNA阳性。对85份弱反应性样本进行HBV DNA检测,其中阳性3份。某国产ELISA试剂检测HBsAg灵敏度为0.5ng/ml,Abbott试剂为0.05 ng/ml。结论我国的HBV感染人群中,有一部分血清HBsAg呈低水平状态存在,并且部分感染者存在病毒复制。国产HBsAg ELISA定性试剂灵敏度较Abbott定量试剂低,因此必须重视弱反应性结果,尤其是位于阳性判断值以下者,灰区设置非常必要。
