A control test using your meter's specific control solution ensures that you are performing tests correctly and receiving accurate results.

Testing with control solution is much like a blood sugar check, except you fill the window on the test strip with a drop of control solution instead of blood.

Run a control test:

• Before using your meter for the first time
• When you open a new vial of test strips
• If you leave the cap off the vial of test strips
• If you drop the meter
• Whenever your result does not agree with the way you feel
• Whenever you want to check the way you are performing your blood sugar checks
• If you have repeated a test, and the blood sugar result is still lower or higher than expected
• When you want to check the performance of the meter or test strips
