control
solution
The control solution is used to test the entire blood glucose monitoring system. This helps to deter-
mine whether the monitor and the test strips are working optimally together and whether the test is
being performed correctly.
Perform the control solution test if you suspect that the blood glucose monitor and/or the test strips
could be faulty or if you have repeatedly measured unusual blood glucose values. Also test the blood
glucose monitor if it has been dropped or is damaged. The control solution is available separately.
Please observe the additional notes in the instructions for using the control solution for the test.
