*The information and data contained in this table were obtained from each manufacturer’s product user guide: Dexcom (Dexcom G6 CGM System User Guide, 2018); Abbott FreeStyle Libre 14 Day Flash Glucose Monitoring System, Summary of Safety and Effectiveness Data (SSED), July 2018; Medtronic (Guardian Connect System User Guide, 2018); Senseonics (Eversense CGM User Guide, 2018). If glucose alerts and readings from the G6 do not match symptoms or expectations, use a blood glucose meter to make diabetes treatment decisions. Fingersticks are required for treatment decisions when you see Check Blood Glucose symbol, during the first 12 hours of sensor use, when symptoms do not match system readings, when you suspect readings may be inaccurate, or when you experience symptoms that may be due to high or low blood glucose. ||G6 readings can be used to make diabetes treatment decisions when taking up to a maximum acetaminophen dose of 1,000 mg every 6 hours. Taking a higher dose may affect the G6 readings. MARD data shown based on calibrations every 12 hours; published MARD with calibration 3-4 times/day: 9.6% (abdomen); 8.9% (arm).
