Does the blood glucose meter need calibration? Under what circumstances should the blood glucose meter be calibrated?

Does the blood glucose meter need calibration? After testing more than 2000 test strips, the accuracy of the blood glucose meter will decrease obviously, so it is necessary to calibrate it. When using the home blood glucose meter, if many abnormal values are found, patients should go to the medical unit in time to compare with the venous blood glucose value; If there are any problems in the use of the blood glucose meter, you can call the after-sales service directly, and the blood glucose meter manufacturer will provide regular proofreading and cleaning services for the blood glucose meter users.

Under what circumstances should the blood glucose meter be calibrated? The photoelectric blood glucose meter has a photoelectric head. Its advantage is that it is relatively cheap, but its disadvantage is that the probe is exposed to the air, which is easy to be polluted and affects the test results. The error range is about plus or minus 0.8, and the service life is relatively short. Generally, it is more accurate within two years. Two years later, it is suggested that patients who are using photoelectric motors go to the maintenance station for calibration.
