(HealthDay)—Every day, millions of people with diabetes—both type 1 and type 2—rely on the results they get from their blood glucose meters to guide their treatment decisions. But, what if those test results were wrong?

Recent research has found that even though a blood glucose monitor meets the U.S. Food and Drug Administration's standards for accuracy to gain device approval, the meter or test strips used in the meter may not perform as well as expected in the real world. And, those errors can have potentially life-threatening consequences.
