The first step: Check if the quality is guaranteed. Learn whether the blood glucose meter has been certified by some authoritative institutions, such as the U.S. Food and Drug Administration (FDA) or the European Union (CE) approval and certification. Such a blood glucose meter will have quality assurance.
The second step: Look at the convenience of the blood glucose meter's operation. The fewer the steps in operating the blood glucose meter, the less error there will be due to improper operation.
The third step: Pay attention to the pain during blood sampling. Choose a blood glucose meter that requires a small amount of blood and allows for multiple sampling sites, which reduces pain, alleviates the patient's fear of blood sampling, avoids emotional fluctuations, and increases the accuracy of measurements with such instruments.
The fourth step: Gain a deeper understanding of the blood glucose meter's measurement principle. Traditional optical method blood glucose meters have their probes exposed to the air, making them easily contaminated, requiring regular inspection, cleaning, and maintenance. However, blood glucose meters using bioelectrochemical methods do not require frequent cleaning and maintenance.
The fifth step: Finally, understand the technology used in the test strips. One aspect is the technology where the test strip undergoes a chemical reaction with the blood glucose. For example, currently available test strips using glucose dehydrogenase technology are less likely to undergo oxidation reactions with oxygen in the air, reducing interference during storage and use.
