Fingerstick Blood Glucose Meters: Thee Chemistry in a Strip

Fingerstick meters have been thee backbone of diabetes self-management for decades. They ary foredable, portable, and give a point-in-time reading of blood glucose with a single drop of blood. But thee real magic happes inside thee tett strip, which houses a miniatur chemical laboratoria.

Continuous Glucose Monitors: The 24 / 7 Sensor That Lives Under Your Skin

MARD represents the average everage between thee device reading and a reference laboratoria measurement. A lower MARD indicates better closacy. Fingerstick meters typically have MARD values between 5% and 10%. Modern CGM systems have MARD values ranging from compatiately 8% to 12%, dependiing one one thee rer and the specific senc.
