In general, blood glucose test strips oxidase test results may be a little more accurate than dehydrogenase. Since glucose oxidase is selective and only oxidizes glucose, the test results will be more accurate. On the other hand, dehydrogenase will be interfered by other sugars, such as hexose, xylose and other sugars, which will cause false high blood glucose in the subjects. So from the enzyme point of view alone, blood glucose test paper oxidase is more accurate than dehydrogenase. However, which test result is more accurate is related to factors such as the manufacturer of the test paper, the product process and the storage of the test paper. Since test strips are oxidized in the air when opened, the accuracy of the test is also reduced when the test strips are oxidized. When using blood glucose test strips, pay attention to the expiration date, and do not use them if they are out of date, otherwise they are also prone to inaccurate results. If patients find abnormalities in blood glucose, it is recommended that they seek prompt medical attention for further examination and treatment under the guidance of a doctor.
