One of the more “fun” pieces I recently had the opportunity to cover for Diabetes Daily was meter accuracy.
“To be fair, all blood glucose meters will only be accurate to the nearest 1 mmol/L (18 mg/dL) of a laboratory result. Which explains why two simultaneous blood glucose checks will likely produce two different results.
Most blood glucose meters must have a mean absolute relative difference (MARD) within 15 to 20 percent of laboratory results. This standard deems these devices a reliable indicator of blood glucose levels and safe to dose insulin from.
Which blood glucose meter can I trust? I conducted an experiment of sorts at home comparing all of the blood glucose monitoring devices that I currently use.”
