Blood sugar test paper expired can be used

If the blood glucose test strip expires, it is not recommended for diabetic patients to continue using it. Because the enzyme in the expired blood glucose test strip will be inactivated, the blood glucose monitoring of diabetic patients may cause inaccurate values, so there is no guiding significance for the adjustment of the hypoglycemic regimen, and it may delay diagnosis and treatment. Therefore, if the blood glucose test strip expires, it is no longer recommended to continue using it. It is recommended to replace the new test strip. At the same time, if a blood glucose meter has been used for a long time, it should be calibrated regularly. It can be compared with venous blood glucose synchronously. If the difference between the value of blood glucose meter and venous blood glucose is more than 1, it indicates that there is a problem with the accuracy of blood glucose meter.
