Measuring principle
The smartLAB
®
global W nG Self-Monitoring Blood Glucose System
is designed to allow rapid measurement of blood glucose by using
an electrochemical biosensor technology. This system employs a
disposable dry reagent strip technology, based on the FAD-binding
glucose dehydrogenase.
Each test strip features an electrode containing FAD-binding glu-
cose dehydrogenase. A capillary blood sample is applied to the col-
lecting area of the strip, and is automatically drawn into the reac-
tion zone, where the FAD-binding glucose dehydrogenase catalyzes
the glucose dehydrogenation. It will produce gluconolactone.
During the reaction, a mediator transfers electrons to the electrode
surface and generates a current. The amount of the current is pro-
portional to the amount of glucose present in the blood sample.
After 5 seconds, the smartLAB
®
global W nG will show glucose con-
centration on the screen
Intended use
The smartLAB
®
global W nG is intended for the quantitative meas-
urement of glucose in venous whole blood or fresh capillary whole
blood from fingertips, palm and forearm. Testing is done outside
the body (In vitro diagnostic use). It is indicated for self-testing
(over the counter [OTC]) by persons with diabetes, or in clinical
settings by healthcare professionals, as an aid to monitor the ef-
fectiveness of diabetes control. The meter should be used only with
smartLAB
®
nG blood glucose test strips.
