(Analytical) accuracy of blood glucose meters and patients: how do they come together?

Having been ignored for the most part, analytical accuracy of blood glucose (BG) meters is now the subject of a considerable series of studies (manuscripts). While the results of these studies show considerable differences between meters, they also show that many meters have good analytical quality, i.e., in the hands of highly trained technicians and optimally controlled environmental conditions, these meters are able to measure BG in blood samples with such precision (as compared with a laboratory method) that a good percentage of them would also fulfill the requirements of the new International Organization for Standardization (ISO) standard (±15%).
