ABSTRACT
The present study evaluated the accuracy of interstitial glucose measurements by flash glucose monitoring (FGM) and continuous glucose monitoring (CGM). Five diabetes patients simultaneously underwent FGM (FreeStyle Libre Pro) and CGM (iPro™2), and their glucose levels were compared with venous blood and capillary blood glucose levels. The range of daily venous blood glucose levels (30 measurements) was 70-245 mg/dL, with a median of 138 mg/dL. There were good correlations of glucose levels measured by FGM (r2 = 0.90, mean absolute relative difference 8.2 ± 5.6%), CGM (r2 = 0.86, mean absolute relative difference 9.2 ± 9.1%) and capillary blood (r2 = 0.87, mean absolute relative difference 7.2 ± 7.2%) with venous blood glucose levels. The accuracy of FGM measurements was also shown against CGM, with 99.9% of the FGM values (1,279 measurements) being within the Parkes error grid zones A and B. The results suggest that the accuracy of FGM is similar to that of CGM, and that FGM is a useful tool for determining daily glucose profile.
