Accuracy Of Bg Detection

The above studies suggest that BG symptoms are not always recognized accurately. Thus, the next question of critical clinical importance is: how well can patients with type 1 diabetes detect hypo- and hyperglycaemia? Even though patients do not always recognize symptoms, ability to estimate BG could conceivably be accurate if patients are adept at using external cues, including information about time of day, timing and amount of recent insulin, food and physical activity. To address this question empirically, the issue of measurement of accuracy needs to be considered. The use of traditional measures of accuracy, such as correlations and deviation scores, is problematic for several reasons34-36. For example, the correlation between subjective BG estimates and objective measures can be quite high, and the
