【摘要】 目的:探讨全自动加样系统对检测结果准确性的影响。方法:将82份抗-TP阳性标本OD值分3组:第1组OD值为0.105～1.000;第2组OD值为1.001～1.500;第3组OD值为1.500以上。将疑为拖带污染的标本进行双孔检测,分析拖带污染的原因。结果:82份阳性标本中,第1组20份(24.4%),第2组20份(24.4%),第3组42份(51.2%),其中有拖带的标本22份(26.8%),第2组2份(9.1%,2/22),第3组20份(90.9%,20/22)。结论:全自动加样系统遇到高浓度抗原、抗体的标本加样时存在有拖带现象。更多还原

【Abstract】 Objective:To investigate the effect of automatic sampling system on detection accuracy.Methods:Divided 82 positive anti-TP samples into 3 groups:the first group with OD 0.105-1.000,the second group with OD 1.001-1.500,and the third group with OD >1.500.Made diplopore detection to suspected towing contaminative samples,and analyzed the possible cause.Results:22 out of 82 samples showed towing phenomenon(26.8%),including 2 samples in the second group(9.1%,2/22)and 20 in the third group(90.90%,20/22).Conclusion:Antigen and antibody at high concentration can lead to towing phenomenon in automatic sampling system.更多还原
