How do you interpret CGM results?
Current research shows that a CV value <36% represents low GV and a relatively stable glucose profile, whereas a CV value ≥36% indicates an unstable glucose profile. SD is the most familiar GV measure and highly correlates with mean glucose and A1C.
What is a good MARD for CGM?
Reported as a percentage, MARD is the average of the absolute difference between these values. The less the MARD is, the closer are the CGM readings to the comparison values. Typically a CGM system with a MARD <10% is regarded to have good analytical performance.
How is MARD calculated CGM?
Thus the MARD is computed using the difference between the CGM readings and the values measured at the same time by the reference measurement system.
How often should I scan my CGM?
The System uses all available glucose data to give you readings so you should scan your Sensor at least once every 8 hours for the most accurate performance. Scanning less frequently may result in decreased performance.
Is GMI the same as A1C?
Glucose Management Indicator (GMI) GMI indicates the average A1C level that would be expected based on mean glucose measured in a large number of individuals with diabetes. Mean glucose ideally is derived from at least 14 days of CGM data. The GMI may be similar to, higher than, or lower than the laboratory A1C.
What is the MARD of dexcom G6?
Dexcom G6 features an overall MARD† of 9.0%. Dexcom CGM use is clinically proven to lower HbA1C, reduce hyper- and hypoglycemia, and increase time in range.
What does a MARD mean?
A sulky mood or fit of petulant bad temper. ‘I’m in a right mard and have already chewed my husband’s ears off about it’
What is MARD accuracy?
The system has a mean absolute relative difference (MARD) accuracy of 12.3% (1). Reported as a percentage, MARD is the average of the absolute error between all CGM values and matched reference values. Lower MARD values indicate greater device accuracy.
How many times can you scan the FreeStyle Libre sensor?
You can use the FreeStyle Libre 2 reader or FreeStyle LibreLink app◊ to scan your FreeStyle Libre 2 sensor and receive your glucose levels and alarms. For a complete glycaemic picture, you must scan your FreeStyle Libre 2 sensor every 8 hours.
