Principles of the Procedure:
The C
ONTOUR
®
N
EXT
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 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 is required.
Comparison Options:
The C
ONTOUR
®
XT system is designed for
use 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 – 7% per hour).

Limitations
Preservatives:
Blood may be collected by healthcare professionals
into test tubes containing heparin. Do not use other anticoagulants
or preservatives.
Altitude:
Up to 6301 meters does not significantly affect results.
Alternative Site Testing:
Not for use with Alternative Site Testing.
Lipaemic Specimen:
Cholesterol concentrations >30.2 mmol/L or
triglyceride concentrations >53.2 mmol/L may produce inaccurate
results.
Peritoneal dialysis solutions:
Icodextrin does not interfere with

test strips.
Xylose:
Do not use during or soon after xylose absorption
testing. Xylose in the blood will cause an interference.
Contraindications:
Capillary blood glucose testing may not be
clinically appropriate for persons with reduced peripheral blood flow.
Shock, severe hypotension, hyperosmolar hyperglycaemia and
severe dehydration are examples of clinical conditions that may
adversely affect the measurement of glucose in peripheral blood.

Interference:
Reducing substances occurring in the blood naturally
(uric acid, bilirubin) or from therapeutic treatments (ascorbic acid,
paracetamol) will not significantly affect results. The limiting concen-
trations of these compounds are listed on your test strip insert.
