Understanding Control Solution Test Results
Important: Please follow your institution’s control solution testing regulations and procedures.
The label on your test strip bottle shows the acceptable ranges for the
Control Solution. The result you get should be inside this range. Make
sure you compare the result to the correct level of control.
When the control solution result is inside the range (See 1A) on the test
strip bottle, your test strips and your meter are working properly.
If your control solution result is not inside the acceptable range, here are
some things you can do to solve the problem:
Troubleshooting Checks
Action
Was the test strip exposed to open air for a
long period of time?
Repeat the control test with properly stored strips.
Was the test strip bottle capped tightly?
This will humidify strips inside. Replace the test
strips.
Is the control solution expired or
contaminated?
Replace with new control solution to check the
performance of the system.
Were test strips and control solutions stored in
cool, dry places?
Repeat the control test with properly stored strips
and/or control solutions.
Did you follow the testing steps properly?
Read Chapter 2 in the manual “Control Solution
Testing” and test again. Stop using the meter if you
continue to obtain the inaccurate results. Call

Expiration date.
This date applies to
unopened bottles only.
Once opened, the control
solution has a shelf life
of 90 days.
6. When the meter beeps,
there is enough control
solution on the strip. The
meter counts down from
5 seconds and will
display the results. Do
not remove the strip yet.
Check if the reading falls
within the range printed
on the test strip bottle.
7. Remove the test strip
and throw it away after
you have compared the
reading to the range
printed on the test strip
bottle.
8. Close the control
solution vial tightly. Wipe
the tip of the control cap
with a tissue to remove
any excess solution.
