Although rare for a meter to be out of calibration, control solution is beneficial to keep on-hand for reassurance. Control solutions test your meter so you know that it is giving you accurate results.

You should perform a control solution test if you experience one or more of the following conditions:

• You suspect the meter or test strips are not working properly.
• You have dropped or think you may have damaged the meter.
• Your blood Glucose test results are not consistent with how you feel.

Check the performance of the meter and test strips by comparing the control solution results with the range printed on the label of the test strip vial. Checking these regularly can ensure your test results are accurate.
