Lifescan Pocket Scan Blood Glucose Monitor System - Manual (Page 32)

Control solution test results are auto-
matically stored with the word contrl
along with the time and date of the
test. (If you use a logbook, indicate
control solution tests by writing “C”
after the result.)
Control solution results
If test results fall outside the range
printed on the test strip vial, repeat
the test. Results that fall outside the
expected range may indicate:
■ Procedural error
■ Control solution that has not been
shaken enough
■ Expired or contaminated control
solution
■ Improper coding of the meter
■ Dirt on the test strip holder or on the
test area beneath the test strip holder
■ Test strip deterioration
■ Expired or contaminated test strip
■ Meter malfunction
■ Extremes in testing temperatures
Note: The control solution range
is shown in two different units of
measure—mg/dL (used in the
United States) and mmol/L (used
in Canada and some parts of
Europe).
