Principles of the Procedure: The
Contour
®
next LINK 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 Contour
®
next LINK
system is designed for use with capillary whole blood.
Capillary samples should be applied directly to the
Contour
®
next test strip. 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
Altitude:
This system has not been tested at altitudes higher
than 20,674 feet (6301 meters).
Limitations
Limitations
Xylose: Do not use during or soon after xylose
absorption testing. Xylose in the blood will cause an
interference leading to inaccurate test results.
Contraindications: The system should not be used
to test critically ill patients and should not be used by
persons with reduced peripheral blood flow. Shock,
severe hypotension, and severe dehydration are
examples of clinical conditions that may adversely
affect the measurement of glucose in peripheral blood.
