Previous studies have demonstrated favourable overall performance of various point-of-care glucose meters in determining glucose values in venous blood samples as compared to laboratory reference values in hospital settings [10,11,[13][14][15][16]; however, data on point-ofcare glucose meter validity according to glycaemic status are limited; therefore, the objective of the present study was to assess the level of agreement of point-of-care measures of venous whole blood glucose with laboratory glucose measures in defining glycaemic status.

“…The conversion of point-of-care glucose values from fresh capillary blood and from venous whole-blood samples (e.g. tests used by healthcare professionals in clinical or hospital settings) to laboratory tests are subject to random measurement errors [9][10][11]. The American Diabetes Association (ADA) recommended an acceptable error range of up to 15% between the values obtained by glucose meter to be tested and those obtained by the laboratory reference method, which was modified subsequently to a maximum error range of up to 5% [12].…”

Aims To assess the level of agreement between point-of-care and laboratory reference glucose values in defining glycaemic status.Methods We analysed 1292 overweight/obese, non-institutionalized participants, aged 40-65 years, in the San Juan Overweight Adults Longitudinal Study. Fasting venous blood glucose was determined using a point-of-care Bayer Contour Blood Glucose Meter and by Vitros System 250 instrument (laboratory). American Diabetes Association thresholds were used to classify participants into normoglycaemia (< 5.6 mmol/l), prediabetes (5.6 to 6.9 mmol/l), or diabetes groups (≥ 7 mmol/l).Results Bland-Altman plot analysis showed a slope of 0.04 (P=0.002) for the regression between the mean difference and the average of the two methods. The slopes were significantly different from zero among people with normoglycaemia (b=-0.57, P<0.001), and prediabetes (b=-0.75, P<0.001) but not among people with diabetes (b=-0.02, P=0.68). When the prediabetes and diabetes groups were merged into one group, the slope was 0.01, and the glucose values remained similar using the two methods (P=0.76).Conclusion Point-of-care blood glucose measurement may be useful to screen people with diabetes, and to assess glucose among individuals with diabetes where blood can be drawn, but laboratory tests are unavailable or untimely.
