Action
High blood glucose level
on an empty stomach,
above 100 mg/dL
(5.6 mmol/L)
2 hours after a meal
over 140 mg/dL
(7.8 mmol/L)
If this high value persists 2 hours
after your last meal, this may
indicate hyperglycaemia (high
blood glucose). Seek medical
attention to coordinate any
measures, if applicable.
High blood glucose level,
possibly ketones
over 240 mg/dL
(13.3 mmol/L)
Conduct ketone test For this
purpose, seek medical attention.
Very high blood glucose
level
over 630 mg/dL
(35.0 mmol/L)
Take another measurement using
a new test strip. If the display is
the same as before: seek medical
assistance immediately.
5.7 Functional check using control solution
The control solution is used to test the entire blood glucose monitoring system. This helps to determine
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
monitor if it has been dropped or is damaged. Control solution is available separately. For the control
solution test, please observe the additional notes in the instructions for use for the control solution.
Important
• Do not use third-party control solution. Correct functioning of your monitor can only be tested using
Beurer LEVEL 3 + LEVEL 4 control solutions.
• Control solution measurements: when using the device, specialist personnel must follow statutory
guidelines.
• Do not apply any blood samples or control solutions to the test strip before inserting it in the monitor.
Performing a functional test using control solution
Warning
To obtain correct results, the measuring device, the test strip and the control solution must be the
same temperature. For the “Functional test using the control solution”, the temperature must be
between 20 °C and 26 °C.
