摘要
目的选择TECAN全自动酶联免疫分析仪检测乙肝核心抗体(HBcAb)的理想检测程序。方法对同一样本设置不同的加样方式、加样顺序,获得相应的数据,比较检测结果以确定理想检测程序。结果 TECAN全自动酶联免疫分析仪检测HBcAb,加样针存在拖带现象,可能造成标本污染,出现假阳性结果,或污染阴性对照,使CO值降低,造成假阴性结果。通过改进加样程序,减少携带概率,避免阴性对照污染,提高检测质量。结论用单独加样方式,先加阴阳对照再加标本的顺序为理想的检测程序。
Objective To select the ideal examination program of the TECAN automatic enzyme immunoassay instrument for detecting HBcAb. Methods The different adding modes and adding sequences were set on the same sample for obtaining the corresponding data. Results In detecting HBcAb by the TECAN automatic enzyme immu- noassay instrument, adding sample needle had the entrainment phenomenon, which could cause the sample contamina- tion,thus led to false positive results or contaminated the negative control to make the CO value decrease and cause the false negative result. The improvement of adding sample program reduced the carrying probability, avoided the negative control pollution and increased the detection quality. Conclusion Adopting the single adding sample mode, and first adding negative and positive control and then sample are the ideal detection program.
