2、经IIFA、EIISA法及IBT法检测,实验组抗dsDNA抗体的阳性率分别为34.29,54.29和44.29;健康对照组抗dsDNA抗体的阳性率分别为0.15,4.46和1.54,ELISA和IBT检出阳性率与IIFA方法比较,差异有统计学意义(P3、A文章编号:16718348(2011)17一l718一O2Comparativeanalysisofdifferentdetectionmethodsforanti—doublestrandedDNAantibodyZhangChunlei,ZhouXiaomei,ZhangShunan,LiiQi,ChenGuibing,LiQingkuan(1.DepartmentofMedicalLaboratory,ShenzhenHospitalofTraditionalChineseMedicine,Shenzhen,Guangdong518020;2.4、DepartmentofMedicalLaboratoryScience,XiangyaSchoolofMedicine,CentralSouthUniversity,Changsha,Hunan410078,China)Abstract:OhjectiveToevaluatethecharacteristicsandapplicationvalueofanti—doublestrandedDNA(dsDNA)antibodyde—tectionbyindirectimmunofluorescentassay(IIFA),enzyme-linkedim5、munosorbentassay(ELISA)andimmunoblottingtest(IBT).MethodsIIFA,ELISAandIBTmethodswereemployedtodetectantidsDNAantibodyinserumsampleofexperimentalgroup(patientswithsystemiclupuserythematosus。n一70)andhealthycontrolgroup(heahhypeople,一650).ResultsDetectionbyIIFA,ELISAandIBTmethods,p6、ositiveratesofanti—dsDNAantibodyinexperimentalgroupwere34.29,54.29and44.29,respec—tively,however,thepositiveratesofthatinthehealthycontrolgroupwere0.15,4.46and1.54,respectively.ComparedthepositiveratedetectedbyIIFAwithwhichdetectedbyELISAorbyIBTmethods,therewerestatisticallysign7、ificantdifferences(P<0.05).ConclusionDetectionofserumantidsDNAantibody,IIFAhashigherspecificityandlowersensitivity,whileELISAandIBThavehighersensitivityand1owerspecificity.Keywords:enzyme—linkedimmunosorbentassay;fluoroimmunoassay;immunobiotting;lupuserythematosus,systemic;anti—8、dsDNAantibody抗双链DNA(doublestrandedDNA,dsDNA)抗体是
