Will blood stay in the air for more than ten seconds affect the blood sugar level?

I will. There are two ways to make a blood glucose meter. One is oxidase method, the other is dehydrogenase method, and the more common method is glucose oxidase method. This kind of test paper includes: Sannuoan blood glucose test paper, Yicheng blood glucose test paper, Kyoto 1640 test paper, Johnson test paper, etc. The best difference is that all bottled glucose oxidase methods are used up within three months after opening the bottle.

Glucose dehydrogenase method, this kind of test paper includes: glucose test paper in Beijing, glucose test paper in Kyoto 18 10, etc. The best difference is that all bottled glucose dehydrogenase methods do not need to be used up within three months after opening the bottle, but can be used up within the shelf life.

This kind of test paper is easy to react with oxygen in the air by glucose oxidase method, and it is easy to get wet after being exposed to air for a long time, which leads to the decline of numerical accuracy. Glucose dehydrogenase test paper is not easy to react with oxygen in the air and is easier to store and use. Generally speaking, the accuracy of glucose dehydrogenase test paper is slightly higher than that of glucose oxidase method, but more specifically, it depends on the brand, research and development strength and so on.

I hope that knowing the difference between these two test paper technologies will help you choose a more suitable blood glucose meter.
