When it comes to blood glucose meters, sugar friends will be concerned about the accuracy of the measured blood glucose value. Second is the price and quality of blood glucose meters and test strips. After all, after buying a blood glucose meter, it can be used for a long time. There are even many brands of glucose meters in the homes of many sugar friends. But the test paper is a consumable item, which is a big expense for sugar friends.

When it comes to the accuracy of the blood glucose meter, the easiest way is to compare it with venous blood: take the blood glucose meter to the hospital, check the venous blood by registration, after drawing the blood, measure the fingertip blood with the blood glucose meter within 5 minutes, and then compare The results of both can be misleading.

So how much is the error value reasonable?

1. When the measurement result of venous blood is below 4.16mmol / L, the error range of the blood glucose meter is ± 0.83mmol / L. For example, the fingertip blood is 3.8, then the measurement result of the blood glucose meter should be between 2.97 and 4.63, which are within the acceptable range.

2. When the measurement result of venous blood is above 4.16mmol / L, the tolerance of the blood glucose meter is ± 15%. For example, if the blood measured by fingertip is 10, then the blood glucose meter's measurement result should be between 8.5-11.5, which is within the acceptable range.
