The Comparative Study on the Results with Different Biochemical Detecting Systems

Objective To explore the comparability of serum enzyme results of different biochemical detecting systems. Methods According to EP9-A file of NCCLS,three biochemical detecting systems,VITROR250,Roche 7600 and HITACHI 7600,were used to detect ALT、AST、ALP and GGT to obtain the correlation coefficient and the linear equation,respectively. Then the coefficient and equation were used to evaluate the system bias between laboratory methods and comparison method. Results The Outcome biases of ALP and GGT could be accepted in three systems,the biases of ALT and AST were not accept- able partly.Conclusion The comparability of ALP and GGT results in 3 detecting systems accorded to evaluation of clinical acceptability.ALT and AST were not compared each other in 2 detecting systems.
