INS and Hypoglycemia: Successive generations of devices have improved sensor accuracy when comparing with laboratory standards (e.g., Yellow Springs Instruments [YSI] glucose analyzer), thereby leading to nonadjunctive status, so that insulin dosing and decision-making around hypoglycemia treatment can be made using some of these devices.3,5,6 With newer CGM technology, whether MARD remains stable throughout dynamic changes in glucose (often associated with exercise and meal ingestion) is up for debate.7
