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.

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:

Up to 20,674 feet (6301 meters) does not significantly

affect results.

Lipemic Specimen:

Cholesterol concentrations >1168 mg/dL or

triglyceride concentrations >4709 mg/dL may produce

inaccurate results.

Peritoneal dialysis solutions: Icodextrin does not

interfere with CONTOUR

NEXT test strips.

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: Capillary blood glucose testing

may not be clinically appropriate for 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.

Interference: Certain substances occurring in the

blood naturally (uric acid, bilirubin) or from therapeutic

treatments (ascorbic acid, acetaminophen) will not

significantly affect results. The limiting concentrations

of these compounds are listed on your test strip insert.
