Objective To evaluate the precision of BREEZE~(TM) glucose monitor and correlation of glucose measurements between fingertip capillary whole blood glucose(CBG)using BREEZE~(TM) glucose monitor and venous plasma glucose(VPG)using autoanalyzer.Methods All samples of venous plasma and fingertip blood from 188 diabetes or non-diabetes patients were detected for glucose level at fasting,30,60 and 120 min postprandial.BREEZE~(TM) glucose monitor and autoanalyzer measured CBG and VPG respectively.Intra-and inter- coefficients of variations were determined using 10 BREEZE~(TM) glucose monitors with normal,slight high and high glucose levels for the three lots of strips.Results The correlation coefficients between CBG and VPG were all higher than 0.950 at fasting and different postprandial time.98.94% of all measurements were in the A zone when using error-grid analysis.The relevant differences between CBG and VPG were less than 5% at different blood glucose concentrations.The intra-and inter-coefficients of variations of blood glucose values at different blood glucose concentrations using different lots of strips were within 5%.Conclusion BREEZE~(TM) glucose monitor provides high accurate and precise glucose readings on fasting and different postprandial time points over a variety of blood glucose concentrations.
