Accuracy of CGM

The accuracy of CGMs fluctuates and is estimated by mean absolute relative difference (MARD). This accuracy estimation is certifiably not an exact worth yet a greater amount of a sign and reference point, since MARD doesn’t consider the recurrence of estimations. However, CGMs with a MARD of under 10 is viewed as acceptable, and all new FDA-endorsed CGMs accomplish this degree of exactness. The outcomes created by CGMs are interpreted differently in contrast to those delivered by customary finger-prick innovation, in light of the fact that CGMs measure the glucose levels in interstitial liquid instead of glucose levels in the vessels inside the fingertips. Additionally, the slack time between real glucose levels and CGM esteems may add to minor contrasts in readings.


The slack time keeps on improving with advances in technology. People should be reminded to look more at glucose moving than depictions of blood sugars.

As promising as CGM innovation seems to be, it doesn’t totally replace finger-prick innovation. Once in a while the CGM device expects you to check with your traditional meter, as well, yet it extraordinarily lessens the requirement for regular finger stick checks.

While some CGMs actually require adjustment using a reading got with finger-prick technology, finger sticks for the most part shouldn’t be needed more than two times every day if the CGM is calibrated accurately.
