Concurrence of System and Laboratory Reference
Table 3-A (Original Adult Study), 3-B (Software 505 Adult Study), 3-C (Original Pediatric Study)
and 3-D (Software 505 Pediatric Study) are categorized by ranges of CGM glucose readings. These
tables describe, 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 Software 505 Adult Study, when CGM readings are within 81 to 120 mg/dL,
you can expect your BG levels are within 81 to 120 mg/dL 72% of time.
