两种生化分析仪部分生化项目检测结果比较

Compar asion of the test results of partial biochemical parameters by two types of chemical analyzer

目的:比较VITROS 250干式化学生化分析仪与HITACHI 7600-020型全自动生化分析仪部分生化项目检测结果。方法:50份样本,分别在两台仪器上测定丙氨酸氨基转移酶(ALT)、门冬氨酸氨基转移酶(AST)、碱性磷酸酶(ALP)、L-γ-谷氨酰基转移酶(GGT)、总蛋白(TP)、白蛋白(ALB)、总胆红素(TBIL)、直接胆红素(DBIL),并记录数据。结果:两种分析方法测定AST、GGT、TP和TBIL的结果差异均无统计学意义(P>0.05),且均具有较好相关性;而ALT、ALP、ALB、DBIL的测定结果差异均有统计学意义(P<0.05)。结论:同一实验室有两台或者两台以上的生化分析仪开展相同的检验项目时,定期对不同分析仪结果之间进行比对和校准,是保证测定结果准确性的必要措施。

Objective：To compare the test results of partial biochemical items verified by VITROS 250 dry chemical analyzer and HITACHI 7600-200 automatic biochemistry instrument.Methods：The parameters including ALT,AST,ALP,GGT,TP,ALB,TBIL and DBIL in fifty samples were analyzed and recorded with these two instruments.Results：There was no statistical significance of the results of AST,GGT,TP and TBIL detected by these two analytical methods（P0.05）,and these results had preferable correlation.While there was statistical differences between the results of ALT,ALP,ALB and DBIL with these two analytical methods（P0.05）.Conclusions：If there are two or more biochemical analyzers to detect the same testing items,it is necessary to compare and calibrate the different testing results regularly to insure the accuracy of testing results.
