Accuracy
1. Bayer Accuracy Evaluation:
To assess the accuracy of the Ascensia C ONTOUR System, 60
fresh fingerstick specimens from people with diabetes were
tested with the Ascensia C
ONTOUR System (12 – 14 readings
per fingerstick) and the YSI 2300 STAT Plus Glucose Analyzer.
The glucose concentration of the samples ranged from 45 to
454 mg/dL with an average of 150 mg/dL. The range of
hematocrits was 32% to 49% with an average of 40%.
