Accuracy: The accuracy of the Ascensia
C
ONTOUR
Blood
Glucose Monitoring System has been assessed in a corre-
lation study conducted by healthcare professionals. In this
study, 108 fresh capillary blood specimens were tested
with the Ascensia
C
ONTOUR
Blood Glucose Monitoring
System by 108 untrained people with diabetes using three
test strip lots. The reference measurement was done on
the YSI Glucose Analyzer. Ascensia
C
ONTOUR
data compare
well with the results from the YSI method.
Regression Statistics (Plasma/Serum Reference):
plasma reference glucose range: 75 to 397 mg/dL
Precision: A study was conducted with the Ascensia
C
ONTOUR
Blood Glucose Monitoring System with fi ve heparinized
whole blood specimens with glucose levels from 40 to
325 mg/dL. Multiple replicates (n=100) were tested using
multiple Ascensia

Blood Glucose Meters and
one lot of Ascensia

Blood Glucose Test Strips. The
following precision results were obtained:
