Performance Analysis
The performance data for the Accu-Chek Performa System (Accu-Chek Performa Meter
with Accu-Chek Performa 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 Performa system meets the EN ISO 15197 requirements.
Measuring Principle
Blood glucose concentrations may be measured in whole blood or plasma. Although you
always apply whole blood to the test strip, your meter displays blood glucose results that
relate to plasma. Please refer to the package insert for information on how the system
works, on the test principle, and on reference methods.
