On Call Extra Control Solution 3 bottles (2 mL/bottle)
Control Solution: Verifies the proper operation of the blood glucose monitoring system by checking the test strips and meter against a pre-calibrated control solution. Control Solution 1 is all you need most of the time. Control Solution 0 and Control Solution 2 are also available if you want to do a level 0 or level 2 test. The three levels of control solution, CTRL 0, CTRL 1 and CTRL 2 are available in the On Call® Extra Glucose Control Solution package which is sold separately.

It is used to confirm that your On Call® Extra Blood Glucose Meter and test strips are working together properly and that you are performing the test correctly. It is important to run a quality control test regularly to make sure you are getting correct results.

Before you first use your meter, to familiarize yourself with its operation.
Before using a new box of test strips.
When you suspect that the meter or test strips are not working properly.
When you suspect that your test results are inaccurate, or if they are inconsistent with how you feel.
When you suspect your meter is damaged.
After cleaning your meter.
