Chapter 2: Control Testing
Why Run Control Tests
Running a control test lets you know that the meter and test strips are working properly. You should run a
control test when:
• You open a new box of test strips
• You left the test strip container open or you think
your strips have been damaged
• Your test strips were stored in extreme
temperatures or humidity
• You want to check if the meter and test strips are
working properly
• You drop the meter
• Your test result doesn’t agree with how you feel
• You want to check if you are testing correctly
About the Control Solution
• Make sure you use the control solution that
matches your test strips (for example, ACCU-CHEK
Comfort Curve control solution (blue liquid) with
ACCU-CHEK Comfort Curve test strips).
• When you first open the bottle, write the date on
the label – the control solution is good for three
months from that date or until the expiration date
on the bottle, whichever comes first.
• Never use control solution that has expired.
• Control solution can stain clothes. If you spill it,
wash your clothes with soap and water.
• Always close the control solution bottle tightly.
• Store at room temperature less than 90° F
(32° C). Do not freeze.
