【摘要】 目的通过梅毒血清学实验室室间质评活动,对实验室开展梅毒血清学检测质量进行评价,以进一步加强性病实验室质量控制和管理。方法将卫生部临床检验中心和广东省皮肤性病防治中心发放的2010～2012年室间质评标本在规定时间内同常规标本同条件下进行测试,将结果回报各检验中心,与预期结果、靶值进行比较。结果参加卫生部临床检验中心的质评成绩为优良,参加广东省皮肤性病防治中心的质评为优秀。结论非特异性梅毒和特异性梅毒抗体同为阳性的质控标本合格率高,单项梅毒抗体阳性的质控标本出现假阴性,临界值和弱阳性标本是影响整体室间质评合格率的主要因素。更多还原

【Abstract】 Objective To join in the activity of external quality assessment in syphilis serologic tests and evaluate the quality of syphilis serologic tests,in order to enhance the quality control and management in Venereal Disease Experimental Laboratory.Methods The external quality assessment samples provided from National Center for Clinical Laboratories and Guangdong Provincial Dermatology Preventive Center from 2010to 2012tested,and routine samples were detected in same conditions with prescriptive time we compared prospective results and target values with the results which have reported to each center of laboratory.Results The external quality assessment grades from National Center for Clinical Laboratories were choiceness and Guangdong Provincial Dermatology Center were excellence.Conclusion The qualified rate of the samples of quality control was high,which both the nonspecific and specific syphilis antibody were positive.False negetive can be existed in samples of QC which non-specific or specific syphilis antibody were alone positive.The main factors for the qualified rate were critical value and weakly positive samples.更多还原
