We studied the difference in glucose levels between capillary (C) and venous (V) whole blood during 75g oral glucose tolerance test (OGTT) in healthy subjects.<BR>The post-loaded glucose levels in capillary blood were significantly higher than those in venous.blood (p<0.01), and the mean values of C-V difference at 30, 60, 90, 120 and 180 min were 24.6, 25.2, 19.3, 17.1 and 9.3, respectively, with the maximum difference at 60 min.<BR>No correlation was found between the magnitude of C-V difference and the levels of glucose in 75 healthy volunteers, although varying C-V differences (-9-52 mg/dl) were observed among them.<BR>Out of 75 subjects 16 had different diagnosis depending on the measurement of either C or V glucose values. Moreover, many subjects, 24 out of 75, were diagnosed to be impaired glucose tolerance (IGT) when evaluated by C blood glucose. These findings indicate that the criteria, recommended by Japan Diabetes Sociaty, for judging C blood glucose levels may be low when compared with those for V glucose.
