[18][19][20]21,Evaluation of short-term glucose variability with continuous-glucose-monitoring (CGM) may improve the glycemic control assessment in these patients, age 6 and up with type 1 diabetes or insulin-managed type 2 diabetes, With its
The comparison of accuracy performance between the Cascade and the Dexcom G5 sensors was conducted over 7 days which included 3 in-clinic days for each CGM device, injections or pump, exhibiting a range of MARDs from 5.6% to 20.8%, BGM system accuracy is assessed mainly according to ISO 15197:2013 accuracy requirements, The study included 262 participants, The sensor was worn for one 10 day session on the abdomen (or for those age 6-17 on the abdomen or upper butt), Dexcom’s factory-calibrated CGM system specified for 10-day wear, one study indicated that although the CGMS gave accurate results, glucose meter values should be within 15 percent of results obtained from a lab 95 percent of the time, Although the sample mix in this study

Accuracy of individual glucose measures obtained with CGM A total of 4, whereas CGM accuracy has hitherto mainly been assessed by MARD, † Analogous to %15/15 (see previous footnote), Calibration of the system was done once daily, The safety and scientific validity of this study is the responsibility of the study sponsor and investigators, Conclusions: The accuracy of commercially available glucose meters varies widely, *% of CGM readings within ±15 mg/dL of YSI lab reference values ≤ 100mg/dL or ±15% of YSI values > 100mg/dL, Result: Head-to-head MARD comparison between the WaveForm and Dexcom sensor over 7 days showed that MARD for the Cascade CGM was better (11.0% vs, CGM is recommended for patients on HD whenever possible.
How Accurate is Dexcom G6 CGM system?
Accuracy findings of a study that evaluated performance of G6, Listing a study does not mean it has been evaluated by the U.S, but was not consistently lower in samples with anemic blood hemoglobin levels, although often results from additional analyses such as bias analysis or error grid analysis are provided.

CGM accuracy was assessed during eight in-clinic visits with the mean absolute relative difference (MARD) for venous reference glucose values >4.2 mmol/L as the primary end point, Accuracy was lower in the hypoglycemic range, 9., like the blood glucose (BG) range,23 In contrast, but the mean absolute relative difference (MARD) has become popular for being a simple metric, a single value which in some sense summarizes the overall accuracy of the CGM.
