Regarding the purchase of blood glucose meters, you really need to be cautious. At present, the common blood glucose meters on the market can be divided into two categories: electrochemical test and light reflection test according to the sugar measurement technology. The former is the electrons generated by the reaction of the enzyme with glucose, and then uses the current counting device to read the number of electrons, and then convert it into a glucose concentration reading. The latter is an intermediate (colored substance) produced by the reaction between enzyme and glucose. A detector is used to detect the intensity of reflected light on the reflective surface of the test paper, and the intensity of these reflected light is converted into glucose concentration with higher accuracy.
Consider the following factors when purchasing a blood glucose meter.
1. Accuracy, first of all, the accuracy of the instrument must be considered. If the test result is inaccurate, it will lead to misleading, and even the tragedy of delayed treatment. If the blood glucose meter on the market is used properly, its accuracy is quite high, but after a period of use, the accuracy of the blood glucose meter may decrease, so it is necessary to maintain and maintain the blood glucose meter regularly.
2. Simplicity, you can choose a blood glucose meter with less operation steps and lower requirements on the operator, and you can use it with only a little training.
3. Test time. Currently, the test time of blood glucose meters on the market is very fast, mostly tens of seconds, or even a few seconds.
4. Test site. Compared with the traditional finger collection method, blood collection from multiple sites can greatly reduce the pain of collection.
5. Memory function, try to choose an instrument with a large memory capacity, so as to check the previous blood sugar situation.
6. The price. The blood glucose meter is a one-time consumption, but it is important to consider the price of blood glucose test strips. At present, the prices of various blood glucose meter tests on the market are not much different, and you can choose test strips that can continue to add blood samples. When the blood sample volume is insufficient, the blood sample volume can be added within the specified time to avoid waste of test paper and save money.
