Principles of the Procedure:
The C
ONTOUR
N
EXT
ONE 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 test
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 the 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 by the user is required.
Comparison Options:
The C

EXT
ONE system is designed
for use with capillary whole blood. Comparison with a laboratory
method must be done simultaneously with aliquots of the same
sample.
NOTE:
Glucose concentrations drop rapidly due to glycolysis
(approximately 5%–7% per hour).
