1. Accuracy identification of blood glucose meters
Many diabetics want to know if their blood glucose meters are accurate? Which brand of blood glucose meter is the most accurate? We can use our own blood glucose meter to test it immediately after going to the hospital to draw blood to test the venous blood sugar, and then we can know it by comparison.
According to the “Chinese Expert Consensus on the Practice of Clinical Operation and Quality Management of Portable Blood Glucose Meters” issued by the Laboratory Medicine Branch of the Chinese Medical Association in 2016, the specific standards are as follows.
When the venous blood glucose concentration in the hospital is <5.5mmol/L, the blood glucose measured by the blood glucose meter is within the range of ±0.83mmol/L, and it can be said that your blood glucose meter is accurate.
When the venous blood glucose concentration in the hospital is ≥5.5mmol/L, the blood glucose measured by the blood glucose meter is within the range of ±15%, and the blood glucose meter can be considered accurate.
The above detectable blood sugar range is 2.2mmol/L-22.2mmol/L, that is, when the blood sugar is particularly high and particularly low, it cannot be compared.
2. How to store test strips to make blood glucose measurement more accurate
Speaking of blood glucose meters, let’s talk about blood glucose test strips that are easy to ignore, which also affects the accuracy of blood glucose measurement A factor.
1. Barrel or boxed blood sugar test strips should generally be used up within 3 months after opening the package. For those with stable blood sugar control and less frequent daily monitoring, it is recommended to choose independent packaging to avoid the remaining test strips reacting in the air and affecting the accuracy. Use barrels or boxes of blood sugar test strips. It is best to use up as soon as possible after opening, and pay attention to close the lid tightly every time.
2. The suitable environment for the storage of blood glucose test strips is below 30°C. If the ambient temperature exceeds 30°C, it should be stored in the refrigerator.
3. Pay attention to keep away from light, away from heat sources, not in the freezer of the refrigerator, and do not get wet.
Storing in excess of the appropriate ambient temperature and humidity will affect the quality of the test strip and the accuracy of the blood sugar value.
