Concurrence of System and Laboratory Reference
Tables 3-A and 3-B are categorized by ranges of CGM glucose readings. This table describes, for each
range of CGM glucose readings, what percentage of paired YSI values were in the same glucose range
(shaded) or in glucose ranges above and below the paired CGM readings. For example, based on the
study, when CGM readings are within 81 to 120 mg/dL, you can expect your blood glucose
Advanced
levels are within 81 to 120 mg/dL 72% of time.
