Do I need to calibrate my glucose meter?

Do I need to calibrate my glucose meter?

There is a basic requirement for blood glucose meters to be calibrated, or coded. In the absence of periodic calibrations the accuracy of any blood glucose meter’s measurements comes into question. Without a reference point to begin with, the instrument may never read correctly.

How do I know if my glucose meter is accurate?

Check your blood sugar level with your meter at the same time that blood is drawn for lab tests. Then compare your meter’s reading with the lab results. Results that are within 15 percent of the lab reading are considered accurate.
