Detection Principle Principle
Blood Glucose Test Strip (hereinafter referred to as Blood Glucose Strip or
Strip) adopts the new biosensor technology and siphon principle. Glucose
oxidase and conductive medium is immobilized in the surface of the electrode;
when the glucose in the blood contacts with the enzyme on the electrode and
the conductive medium, specific reaction will be initiated and instantaneous
current will be produced; the size of current is directly proportional to the
glucose concentration, and through the Blood Glucometer, the current signal is
converted into blood glucose value, which is displayed on the screen.
