Concurrence of G6 and Laboratory Reference
Tables 3-A to 3-D categorize concurrence by CGM reading and YSI
values. Tables 3-A and 3-B describe, (row percent), for each range
of CGM glucose readings, what percentage of paired YSI values was
in the same glucose range (shaded) or in glucose ranges above and
below the paired CGM readings. For example, Table 3-A shows that
for adults, when CGM readings are within 81 to 120 mg/dL, you can
expect your blood glucose levels are within 81 to 120 mg/dL 70 % of
time. Tables 3-C and 3-D describe (column percent), for each range of
YSI values, what percentage of paired CGM readings was in the same
glucose range (shaded) or in glucose ranges above and below the
paired YSI values. For example, Table 3-D shows that for pediatrics,
when YSI values are within 81 to 120 mg/dL, you can expect your CGM
readings to be within 81 to 120 mg/dL 78% of time.
