Capability analysis of three POCT glucose meters

Objective To evaluate the capability of different POCT glucose meters and to understand the difference between the venous blood glucose results by POCT glucose meters and the blood glucose results tested by biochemical analyzer.Methods The accuracy,reportable range,comparison with biochemical analyzer were detected by the different instruments with heparin whole blood.All statistical analyses were performed with SPSS version 11.0 statistical software.Results The within-CV% of Sure-Step,Accu-Chek Active,ONE Touch POCT glucose meters were 2.36%-2.54%,1.06%-1.25%,4.20%-4.66% respectively.The regression equations with biochemical analyzer(AU5400) were Y=1.029 9X+0.178 9,Y= 0.861 1X+0.527 6,Y=0.926 7X-0.069 7 respectively.In the medical decision level,the differences from comparison with the target detection systems was 20%.Conclusion There is significant differences between different POCT glucose meters and blood glucose and biochemical analysis of the results detected.POCT glucose testing method can be used as the selection,but not a substitute for blood glucose measurement by biochemical analyzer.
