How effective is the blood glucose meter?

Generally, individual users of blood glucose meters on the market can't calibrate themselves, but the commonly used electrode method machines basically don't need to do much calibration work, and their own machines are generally high in accuracy. This thing is relatively simple.

The main problem of blood glucose meter deviation is actually test paper. Due to the control of raw materials and production process, each batch of test strips is different. Therefore, enterprises will use different calibration codes for calibration, but they cannot guarantee that all interval results are 100% accurate. Therefore, the blood glucose meter has an acceptable national standard error range.

If you are not very confident about your blood glucose meter, I suggest you go to the hospital and compare it with the biochemical analyzer to see the approximate deviation ratio of your blood glucose meter. Objectively speaking, this only reflects the degree of cooperation between your test paper and the machine. Other batches of products cannot be guaranteed, so generally, the better products will be compared in three different batches to determine the accuracy. In addition, it is important to test at the same time as possible when testing, so that the comparison is meaningful. After all, blood sugar changes all the time.

If the deviation is large, I suggest you call the manufacturer directly after sale, and they will find a way to deal with it. As for repair or replacement, it depends on how the warranty agreement is determined.
