The working principle of Blood Flucose Meter and precautions for Blood Flucose Meter

The blood glucose meter is an electronic instrument that measures the blood glucose level. It is mainly used to detect the blood glucose concentration in diabetic patients. Usually, the blood glucose meter can be used to grasp the blood glucose concentration level in time, so as to adjust the diet and exercise in time to control the continued development of the disease. Therefore it is essential for diabetics.
Blood glucose meters are mainly divided into two categories: electrochemical method and photochemical method:
1. The electrochemical method uses the principle of detecting the current signal generated during the reaction to reflect the blood sugar level. The electrons generated by the reaction between enzyme and glucose pass the current counting facility to read the number of electrons, and then convert it into a glucose concentration reading.
2. The photochemical method is to detect the color change of the test strip during the reaction process to reflect the blood sugar level. Through the intermediate produced by the reaction of enzyme and glucose, the detector is used to detect the intensity of the reflected light on the reflective surface of the test paper, and the intensity of the reflected light Converted into glucose concentration.
Why is the blood sugar inaccurate? Pay attention to the following points when measuring:
1. The blood glucose values measured at different times are not comparable. It is recommended that you check blood sugar at home or compare data at the same time every day as much as possible.
2. Affected by insomnia, mood swings and other reasons. The fasting blood glucose measured under these conditions cannot reflect the real situation and must be treated symptomatically instead of adjusting blood sugar lowering drugs.
3. Improper selection of disinfectant, disinfect with iodine or iodophor, the latter will react with the test paper, resulting in high test results. Therefore, 75% alcohol should be used to sterilize blood collection, and the test should be performed after the alcohol has dried out.
4. The blood sampling method is incorrect. If the blood sampling volume is insufficient during the test, the test will fail or the test result will be low. You need to replace the test strip and perform the measurement again. If the blood drop is too large and overflows the measurement area, it will also affect the measurement result. It is recommended that the needle penetration depth should be appropriate when taking blood from the finger to avoid squeezing the finger.
5. No code adjustment before the test. Before the test, check and adjust the code displayed on the blood glucose meter to be consistent with the code on the test strip packaging box.Blood Flucose Meter  is a must-have instrument in your home.
