Abstract:
Objective To compare the evaluation effect ,clinical feasibility and influencing factors of two methods on comparative analyzing the blood glucose measurement of glucose meter and automatic analyzer .Methods 61 diabetic or non-diabetic patients were recruited in this study .All subjects were drawn 2 mL fasting venous blood using EDTA-K2 tubes following an 8~12 h over-night fast .One drop of venous whole blood was used to measure the blood glucose concentration (VBG)with the meter and the rest of blood was centrifuged for detecting the plasma glucose (VPG)by automatic analyzer (HITACHI-7600) .The capillary blood was taken by finger stick to test blood glucose(CBG)using the same meter within 5 min after the venous blood collection .Taking the VPG as the reference ,to calculate the respective bias of VBG and CBG .Correlation of VPG with VBG or CBG was analyzed .The clinical acceptance of glucose meter readings was evaluated by Parkes error grid analysis .Results Both VBG and CBG measured by Accu-Chek Performa glucose meter were highly correlated with VPG ,with correlation coefficient 0 .991 and 0 .989 respectively .All the measurements satisfactorily met the GB/T 19634-2005 criteria and all the results were clinically accepted .Conclusion To com-pare the results of blood glucose measured by glucose meter and automatic analyzer ,venous blood sample is recommended because of the same blood resource ,convenience of operation and possibility of making blood samples with extremely low or high glucose concentration .
