The glucose measurement is based on the following
methodology:
1. G Enzymes(oxidized form) –––>
Gluconic Acid + Enzymes(reduced form)
2. Enzymes(reduced form) + Ferricyanide ––>
Enzymes(oxidized form) + Ferrocyanide
-e
-
3. Ferrocyanide —————> Ferricyanide
Electrode
The current generated at the electrode is proportional to the
glucose concentration of the sample.
