Comparing control solution results

If test results fall outside the range printed on the test strip vial, repeat the test. Out-of-range results may be caused by one or more of

the following:

Error in performing the test.

Failure to shake the control solution vial well.

Expired or contaminated control solution.

The meter, test strips, or control solution are too warm or too cold.

Failure to discard the first drop of control solution and wipe the dispenser tip clean.

Improper meter coding.

Test strip deterioration.

Meter malfunction.

CAUTION: If you continue to get control solution test results that fall outside of the range printed on the vial, the system may not be working properly. Do not use the meter. Call the OneTouch® Customer Care Line at 1 800 663-5521.
