Error standard：

If the error of the rapid blood glucose meter（Household Intelligent Digital Glucometer Testing Equipment） is within 20%, it is generally considered that it will not affect the change of treatment measures, so it is acceptable. Therefore, the World Health Organization's requirement for the error of the blood glucose meter is within 20%.

According to the national standard GB/T 19634-2005 for blood glucose meters issued by the General Administration of Quality Supervision, Inspection and Quarantine of China, the blood glucose meter can be considered qualified if the deviation of 95% of the results measured by the blood glucose meter meets the following requirements:

When the test range is less than or equal to 4.2mmol/L, the allowable deviation does not exceed plus or minus 0.83mmol/L

The test range is greater than 4.2mmol/L and the allowable deviation does not exceed plus or minus 20%

The difference between batches of blood glucose test strips The difference between batches of different batch numbers of blood glucose test strips should not be more than 15%

Key technology of Household Intelligent Digital Glucometer Testing Equipment:

Stability (CV value, coefficient of variation): Stability is an important indicator for evaluating the quality of blood glucose meters. Due to the relatively large error of blood glucose meters, for example, blood glucose is 10, 8 or 12 measured according to national standards can be considered accurate. However, if these two results are measured by a machine, it means that the stability of the machine is not good, and the poor stability will make the measurer confused, and it is difficult to effectively guide the patient to take the treatment plan. Therefore, the stability of the blood glucose meter is very important. Stable blood glucose meter indicates that the stability of the test strip enzyme is good. Therefore, the more advanced the culture enzyme technology, the better the product stability.
