blood
glucose test is based on measurement of electrical current
caused by the reaction of the glucose with the reagents on
the electrode of the strip. The blood sample is drawn into
the tip of the test strip through capillary action. Glucose
in the sample reacts with FAD glucose dehydrogenase
(FAD-GDH) and a phenothiazine derivative as a mediator.
Electrons are generated, producing a current that is
proportional to the glucose in the sample. After the reaction
time, the glucose concentration in the sample is displayed.
No calculation is required.

system evaluations
should be done with venous and capillary whole blood.
Comparison to a laboratory method must be done
simultaneously with aliquots of the same sample. Note:
Glucose concentrations drop rapidly due to glycolysis
(approximately 5% to 7% per hour).
