How to Check That Your Blood Glucose Meter Works As Expected

You can do regular checks with the liquid control solution that comes with your blood glucose meter or test strips to see if your device is functioning properly. The control solution may be used when: 

• You open a new container of test strips
• If you drop your glucose meter
• If you get unexpected results

If your blood glucose meter returns an error after completing an electronic check, please follow the instructions provided with the device or review the manual for assistance.

If you are unable to determine the cause or resolution of the error message, please contact the manufacturer's support team. The contact information is located in your device manual. 

Please contact your doctor or laboratory where you have your blood tests completed if you have doubts about the accuracy of your blood glucose meter. In order to verify accuracy, please bring your blood glucose meter with you. After asking your doctor or a lab technician to verify that you are using your blood glucose meter  properly, do a blood sugar test with your device. Then, follow the advice from your medical provider to determine if a laboratory verification test is needed, and compare your results. The results from your blood glucose meter and the lab should be the same.
