Performance Analysis
The performance data for the Accu-Chek Aviva System (Accu-Chek Aviva Meter with
Accu-Chek Aviva Test Strips) were obtained using capillary blood from diabetic patients
(method comparison, accuracy), venous blood (repeatability) and control solution (reproducibility).
The system is calibrated with venous blood containing various levels of glucose. The reference
values are obtained using the hexokinase method. For method comparison, the results were
compared with results obtained using the hexokinase method with deproteinization (automatic
analyzer). The hexokinase method is traceable to an NIST standard.
The Accu-Chek Aviva System meets the EN ISO 15197 requirements.
Blood glucose concentrations may be measured in whole blood or plasma. Although you always
apply whole blood to the test strip, the meter displays blood glucose results that relate either
to whole blood or plasma. To see whether your blood glucose meter displays results relating to
whole blood or plasma, see the package insert that came with your test strips. You will also find
information on how the system works, on the test principle and on reference methods.
