Control Solution Test; Control Solution Range - Lifescan SureStep blood glucose monitoring system Owner's Booklet

When the control solution test result
is within the control range, you are
ready to test your blood. Your con-
trol solution test will be stored in
the meter memory. Record control
solution tests in your logbook by
placing a C next to the result to
indicate a control solution test.

Control Solution Range

If test results fall outside the expected
range, repeat the test. Results that fall
outside the expected range may
indicate the system is not working
properly. Some possible causes are:
Procedural error
Expired or contaminated
control solution
Test strip code and meter code
do not match
Dirty meter or test strip holder
Test strip deterioration
Meter malfunction
Control solution that is outside
of the temperature range 59–95˚F
(15–35˚C)
