摘要: 目的 分析核酸检测技术在盐城地区献血者血液筛查中的应用效果及必要性。方法 选取在2015年3~12月盐城地区采集的至少一种酶免试剂阴性的无偿献血者标本55 186例,采用 Roche Cobas s201检测系统和中山大学达安基因股份有限公司的仪器及试剂开展HBV DNA、HCV RNA及HIV RNA联合NAT检测,采用6/8人份混样池血液筛查核酸检测。对筛查阳性的部分标本送至江苏省血液中心进行确证。结果 至少一种酶免试剂阴性的55 186份标本共检测了7 965个pool,其中罗氏系统检测3 930个pool,检出47个反应性pool,pool阳性反应率为1.20%。达安系统检测4 035个pool,检出39个反应性pool,pool阳性反应率为0.97%。拆分检测共筛查出42份核酸反应性标本,总反应性率为0.076%。其中罗氏核酸检测系统反应性率为0.12%,达安核酸检测系统反应性率为0.047%,两者差异有统计学意义,P<0.05。36份送检标本中,有25份被确认为HBV DNA 阳性,确认阳性率为69.44%。所有标本中无HCV RNA 和HIV RNA 的检出。结论 在常规血清学检测的基础上进行核酸检测,能降低常规血清学检测漏检率,提高血液安全性。

Abstract: Objective To investigate the necessity of nucleic acid test (NAT) and its significance in blood screening of donators in Yancheng district. Method sA total of 55 186 blood samples with at least one negative ELISA were selected in 2015. The NATs were performed in all samples based on Roche Cobas s201 nucleic acid amplification testing system (Roche system),the HBV DNA,HCV RNA and HIV RNA were individually detected with DAAN system in the pooled blood of 6 or 8 samples. The positive samples in the screening were subjected to confirmatory tests in the Province Blood Center. Results Totally,7 965 pools were tested by NATs in the samples that showed at least one negative ELISA. Among them,47 (1.20%) positive pools of 3 930 pools were found by Roche system. In the 4 035 pools tested by DAAN system,39 (0.97%) positive pools were noted. 42(0.076% ) samples were found to be positive in individual NATs. The positive rates of Roche system and DAAN system were 0.12% and 0.047%,respectively (P<0.05). In 36 samples,25 (69.44%) were confirmed to be HBV DNA positive,while no HCV RNA and HIV RNA were found. Conclusion Nucleic acid test is recommended following serological detections,which would cover the shortage of serological tests and ensure the blood safety.
