Understanding Out‑of‑Range Control Results
WARNING
The control ranges apply only to control results. They only indicate that your test strips and meter
are working properly. Do not use control results to interpret blood glucose results.
If the control result is not inside the acceptable range (printed on the test drum container), do not use the
meter until you solve the problem. Here are some things you can check:
Troubleshooting Checks Action
1. Is the test drum or control solution past the
“Use by” date or discard date?
If either is past the “Use by” date or discard date,
throw it away.
2. Was the control solution bottle always closed
tightly?
If you think it may have been uncapped for some
time, replace the control solution.
3. Were the meter, the test drum, and the control
solution properly stored?
Repeat the control test with properly stored meter, test
drum or control solution.
4. Did you wipe the tip of the control solution
bottle with a tissue prior to use?
Wipe the tip of the bottle with a tissue. Repeat the
control test with a fresh drop of control solution.
5. Did you use a drop of control solution that
formed at the tip of the bottle?
Repeat the control test with a fresh drop of control
solution. Use a drop that has formed at the tip of the
bottle.
6. Did you freshly apply the control solution to
the washable object?
If the control solution was left exposed on the surface
for any length of time, repeat the control test with a
new, freshly applied drop.
