Comparing Control Solution Results

If test results fall outside the range printed on the test strip vial, repeat the test. When using control solution mode, very high or very low readings will be displayed as a number rather than a “HIGH” or “LOW” warning screen and stored in the logbook as “Control Solution High” or “Control Solution Low”. 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 bottle well.

•Expired or contaminated control solution.

•Meter, test strips, or control solution that 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.

•Testing blood in Control Solution mode.

CAUTION: If you continue to get control solution test results that fall outside of the range printed on the test strip vial, the system may not be working properly. Do not use the meter.
