目的分析济南市无偿献血者HBV感染情况,为隐匿性乙型肝炎(乙肝)的检测提供依据。方法选择2010年6月—2012年12月采集的无偿献血者血液标本207 705份,均经酶联免疫吸附剂测定(enzyme linked immunosorbent assay,ELISA)筛查,经筛查后HBsAg、抗-HCV和抗-HIV-1/2无反应性及仅1种试剂为反应性的标本共203 606份,进行核酸扩增技术(nucleic acid amplification techniques,NAT)检测。结果 ELISA检测HBsAg阳性1 059份,阳性率0.510%;NAT检测NAT阳性130份,阳性率0.064%。检出HBV DNA阳性标本74份,阳性率64.910%。结论 HBV感染仍是导致血液淘汰的重要原因之一,通过NAT检测,可以极大地增加隐匿性乙肝的检出率,降低血液残余风险。要加强采血前征询及HBsAg快检工作,提高实验室检测水平,确保血液安全。
Objective To analyze the status of HBV infection in blood donors in Jinan City and provide evidence for the detection of occult hepatitis B (hepatitis B). Methods Totally 207 705 blood samples collected from June 2010 to December 2012 were collected by enzyme-linked immunosorbent assay (ELISA). After screening, HBsAg, anti-HCV And 203 606 copies of non-anti-HIV-1/2 non-responsive and only 1 reagent-reactive samples. Nucleic acid amplification techniques (NAT) were performed. Results 1 059 HBsAg positive samples were detected by ELISA. The positive rate was 0.510%. NAT was detected by NAT in 130 samples with a positive rate of 0.064%. 74 HBV DNA positive samples were detected, the positive rate was 64.910%. Conclusions HBV infection is still one of the most important causes of blood elimination. NAT detection can greatly increase the detection rate of occult hepatitis B and reduce the residual risk of blood. To strengthen pre-blood consults and HBsAg quick check work to improve laboratory testing to ensure blood safety.
