A positive result, in the absence of unequivocal hyperglycemia, should be confirmed by a repeat of any of the above methods on a different day.

But of course we have a way to measure that now on a continuous basis, with a sensor that detects blood glucose, and it's important because we could detect hyperglycemia that otherwise wouldn't be known, And you can see the red dots, in this particular patient's case, were finger sticks, which would have missed both ends.
