Comparative analysis on results of blood glucose detected by Hitachi 7170 and Hitachi 7600 biochemical analyzers

Objective To discuss the comparability of blood glucose(GLU) results detected by different detection systems.Methods According to NCCLS document EP9-A2,3 biochemical testing systems including system 2-3(Y1-Y2,comparative testing systems) and system 1(X,targeted testing system,which was composed of Hitachi 7600 biochemical analyzer P1,maker reagents,C.f.a.s.calibrator and BIO-RAD quality control material),were used to obtain the correlation coefficient and the linear regression equation.The value of GLU in the patient′ s serum was detected by the three systems.Then the coefficient and the equation were used to evaluate the system bias between the comparative testing systems and the targeted testing system.The comparability of different testing systems was judged by half of the CLIA′ 88 standard.Results The variance analysis showed the results between various detection systems had no significant difference(P0.05) and were significantly correlated(r20.95).The results showed good comparability.The deflection evaluation on detection results was clinically acceptable.Conclusion There is good comparability among the results of GLU detected by 3 different testing systems in our hospital.
