Recently, the FDA gathered with experts and industry representatives to discuss the accuracy of blood glucose meters. FDA guidelines currently state that blood glucose meters should measure blood glucose within + or - 20% of the actual value. For example, if your bG is 200 (actual value) your meter should measure between 240 and 160. Experts are now questioning this disparity and the FDA is now considering tightening the tolerance to 15% or even 10%.
The same model using a 15% tolerance would yield bG values between 230 and 170, while a 10% tolerance would yield bG values between 220 and 180.
I don't know about you, but I'm banking on that 10% tolerance as the standard. After all, it's our lives in the balance.
