Sensors are designed for wear period ranging frem 7 days (Dexcom G6 / G7) to 14 days (Abbott Freestyle Libre 2 / 3) and even 180 days for implantables sensors like the Eversense (which requires insertion and removal by a healtcare provider). Sensor creasy is typically assessed using the Mean Absolute Relative Difference (MARD). A lower MARD indivates better disacy. Dexccom G6 has a MARD ard 91%, Freestylfiles 2 aroud 9.210,6%, and thele everseste about 8.5%.
