目的调查常州地区单采血小板献血者抗丙型肝炎病毒(HCV)抗体的阳性率,探讨单试剂检测和双试剂检测对抗HCV抗体阳性检出率的差异。方法应用酶联免疫吸附试验(ELISA)法检测单采血小板献血者血清中的抗HCV抗体,对抗HCV抗体的阳性献血者,应用荧光定量聚合酶链反应(FQ-PCR)技术检测其血清HCV-RNA含量。结果本地区单采血小板献血者抗HCV抗体阳性率低于外来人员(χ2=23.59,P<0.01)。单试剂检测抗HCV抗体阳性献血者的HCV-RNA阳性率低于双试剂检测组(χ2=14.09,P<0.01),单试剂检测组的HCV-RNA含量也低于双试剂检测组(t=5.29,P<0.01)。结论在没有核酸检测的条件下,对血小板献血者抗HCV抗体进行双试剂检测很有必要。
Objective To investigate the positive rate of anti-hepatitis C virus (HCV) antibody in blood samples of apheresis platelets from Changzhou area, and to explore the difference of positive detection rate of anti-HCV antibodies between single-reagent and double-reagent. Methods Serum anti-HCV antibodies were detected by enzyme-linked immunosorbent assay (ELISA) in patients with positive blood donors who had anti-HCV antibodies. The serum HCV- RNA content. Results The positive rate of anti-HCV antibody in blood platelets from PBLs in this area was lower than that of non-human (χ2 = 23.59, P <0.01). The positive rate of HCV-RNA of single-agent-test anti-HCV antibody-positive blood donors was lower than that of double-agent test (χ2 = 14.09, P <0.01) 5.29, P <0.01). Conclusion In the absence of nucleic acid detection, it is necessary to test dual-labeled anti-HCV antibodies against platelet donors.
