Glucose measurement, answer 7

Question 7: For glucose, the limits of agreement were -2.07 to 2.79 mmol/L. How can this be interpreted?

Suggested answer:

We estimate that differences between blood glucose measured by capillary blood and in the laboratory differ by at most 2.07 mmol/L in one direction and at most 2.79 mmol/L in the other direction, for 95% of subjects.

It is not clear from the abstract which direction is which, but the differences are for capillary glucose minus laboratory glucose. Hence we estimate that capillary glucose may exceed laboratory glucose by up to 2.79 mmol/L and that laboratory glucose may exceed capillary glucose by up to 2.07 mmol/L.
