Concurrence of System and Reference (YSI vs. GM)
The percentage of concurring glucose values (YSI vs. GM) in each glucose reference range is
presented for each YSI range in Table 7. For example, when the YSI glucose results are within the
81 to 120 mg/dL range, you can expect the GM values were less than 40 mg/dL 0.2% of the time,
between 40 and 60 mg/dL 1.8% of the time, between 61 and 80 mg/dL 9.0% of the time, between
81 and 120 mg/dL 61.4% of the time, between 121 and 160 mg/dL 26.7% of the time, between 161
and 200 mg/dL 0.8% of the time, and above 201 mg/dL 0.0% of the time.
