A glucose meter is an instrument used to monitor blood sugar levels, and the test strips used are called blood glucose test strips. The principle of glucose meter is mainly divided into two categories: photometric method and electrochemical method. Photometric method blood glucose meter has good stability and accuracy, while electrochemical method blood glucose meter has large differences in price, accuracy, and stability compared to photometric method blood glucose meter.
A blood glucose monitoring device is an instrument used to measure blood glucose levels. Home blood glucose meters on the market are mainly divided into two categories: electrochemical method and light reflection technology.
Blood glucose meters are instruments used to monitor blood glucose levels, and the test strips used are called blood glucose test strips.
The principle of blood glucose meter is mainly divided into two categories: photometric method and electrochemical method.
Photometric method blood glucose meters are similar to CD players, with a photoelectric head. This type of blood glucose meter is relatively inexpensive, but the detection head is exposed to air, making it susceptible to contamination and affecting test results. The error range is ± 0.8 Therefore, the light hole must be cleaned frequently, and it is recommended to calibrate it at a maintenance station after two years of use.
Electrochemical method blood glucose meter can avoid contamination, and the error range is ± 0.2. Normal use does not require calibration.
(1) Should understand the types of blood glucose meter. Blood glucose meters are divided into two categories according to their working principles: photometric method and electrochemical method.
Photometric method HB meter has good stability and accuracy;
Due to differences in electrode materials and built-in correction systems, the price, accuracy, and stability of electrochemical method hb meter has large differences, and this type of blood glucose meter requires a small blood volume and quick test results (several seconds).
(2) Attention should be paid to the cost performance, including the price of test strips.
(3) Attention should be paid to after-sales service, and test strips should be easily available.
(4) When buying a blood glucose meter, you should carefully read the instructions for use, understand the characteristics and special requirements of the instrument, and communicate with professionals in case of any questions during the testing process.
It is best to test at room temperature.
Avoid placing the instrument near electromagnetic fields (such as mobile phones, microwave ovens, etc.).
The amount of blood collected should not be too much or too little (especially for photometric method HB meter).
The battery should be checked frequently, and it should be replaced in time to avoid battery leakage, corrosion of the battery's positive and negative poles, and even endanger the blood glucose meter movement.
Handle with care during use to prevent strong vibration and damage caused by falling.
Under normal use, the blood glucose meter cannot be leaked with water. If it leaks water, the battery must be removed, and the water must be thoroughly removed before continuing to use.
HB meter is mostly used in general outpatient clinics, endocrinology, emergency, and laboratory departments of major hospitals.
