摘    要:目的:在临床检验工作中发现部分胶体金免疫法粪隐血阴性结果与临床诊断不符,其阴性结果有待于进一步分析处理。方法:将临床工作中胶体金免疫法粪隐血阴性标本分成外观正常组和异常组两组,用匹拉米同化学法进行复检,以发现免疫法中的假阴性结果。结果:胶体金免疫法粪隐血阴性颜色正常组与化学法匹拉米同复检结果一致,而胶体金免疫法粪隐血阴性颜色异常组与化学法存在较大差异。结论:对胶体金免疫法粪隐血阴性而颜色异常时需结合运用化学法进行复检,以避免假阴性结果。

Abstract:Objective:In the clinical laboratory work,we had found that the results of some of colloidal gold immunoassay fecal occult blood-negative were different from those of the clinical diagnosis,and its negative results needed to be further analysed and processed.Methods:In clinical work,colloidal gold immunoassay fecal occult blood-negative samples were divided into normal and abnormal appearance of two groups,and Pyramidon chemical re-examination conducts a review to find false negative results of immunosorbent assay.Results:Colloidal gold immunoassay fecal occult blood-negative group with normal color was consistent with pyramidon results with chemical re-examination,but colloidal gold immunoassay fecal occult blood-negative group with the abnormal color was quite different from chemical method.Conclusion:Colloidal gold immunoassay fecal occult blood negative for the abnormal color needs to combine chemical methods to re-examine,It can conduct a review in order to avoid false negative results.
Keywords:Fecal Occult blood test  Colloidal gold immunoassay  False-negative  Pyramidon
