Performance verification of NAG detected by automatic biochemical analyzer

Objective To verify the analytical performance of NAG detected by Olympus AU2700 automatic biochemical analyzer.Methods The precision,functional sensitivity,linearity,clinical reportable range,reference interval were validated,according to Clinical and Laboratory Standards Institute(CLSI)documents(EP5-A2,EP6-A and C28-A2).Results The total coefficients of variation of high and low NAG concentration samples were 6.05% and9.50% respectively,functional sensitivity was 0.72 U/L,linearity was 1.5-196.0 U/L,clinical reportable range was 0.72-1 960.00 U/L,and reference interval was 0.3-12.0 U/L.Conclusion The analytical performance of NAG detected by Olympus AU2700 automatic biochemical analyzer is consistent with the statement offered by manufacturer,it is usable for clinical testing.
