Abstract
The present invention provides a method for determining concentration of blood glucose by using the change in the rising time. The chemical reaction between the blood glucose and enzyme within the test strip to generate the analog source that used to determine the concentration of the blood glucose in the measuring meter. Thus, the rising curve can be obtained after the analog source is treated, such that the concentration of the blood glucose can be determined.
