"Thank you for contacting Accu-Chek.
Please be aware that performing a control test in your home environment cannot by compared to performing a control test in a laboratory, as the strict laboratory testing conditions are not met in the home environment. This means that achieving the target reading of 6.67 mmol/l is not possible. Due to these factors a target range has instead been calculated. This range takes into consideration the effects of temperature deviations and possible sources of contamination. The specific target range for the Accu-Chek Compact Plus control solution is printed on the peel-off label attached to the drum container.
Please see below important information about performing the control solution test:
Treating the control solution properly:
The solution is filled into the bottle under microbiologically controlled (low germ) conditions. To avoid contaminating the solution, do not touch the tip of the bottle with your fingers, the test strips or the surface onto which you apply the control solution. Contaminated control solution can produce incorrect results.
Use only control solution that is within its expiry date. Expired control solution can produce incorrect results. The expiry date is printed on the bottle.
Store the control solution between +2 and +30°C. Control solution that is stored outside this range may become unusable before it reaches its expiry date.
If you store and handle the control solution properly, it will remain stable for 2 months after opening. However, do not use control solution that is past its expiry date, which is printed on the bottle.
The control solution must be at the ambient temperature when you perform a control test. If you keep the control solution in a refrigerator, leave it to stand at ambient temperature before you perform a control test. Cold control solution can produce incorrect results.
Please also note:
Reproducibility (day-to-day imprecision)
The mean imprecision is < 2%. In a typical series of tests a standard deviation of 0.15 mmol/l was obtained with a glucose concentration of 8.6 mmol/l.
Calibration
The system (meter and test strips) is calibrated with venous blood containing various glucose concentrations. The reference values are obtained using the hexokinase method. This reference method is traceable to a NIST standard by means of the ID-GCMS method, the method with the highest metrological quality."
