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

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 (P>0.05),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 (P<0.05).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.
