INTENDED USE
The CONTOUR®NEXT ONE blood glucose monitoring system is 
intended to be used for the quantitative measurement of glucose in 
fresh capillary whole blood drawn from the fingertips or palm. The 
CONTOUR NEXT ONE blood glucose monitoring system is intended 
to be used by a single person and should not be shared. The 
CONTOUR NEXT ONE blood glucose monitoring system is intended 
for self-testing outside the body (in vitro diagnostic use) by people 
with diabetes at home as an aid in monitoring the effectiveness of a 
diabetes control program.
The CONTOUR NEXT ONE blood glucose monitoring system should 
not be used for the diagnosis of or screening for diabetes or for 
neonatal use. Alternative site testing (palm) should be done only 
during steady state times (when glucose is not changing rapidly). The 
CONTOUR®NEXT test strips are for use with the CONTOUR®NEXT ONE 
blood glucose meter to quantitatively measure glucose in fresh 
capillary whole blood drawn from the fingertips or palm.
The system is intended for in vitro diagnostic use only.

About Meal Markers
During a blood sugar test, you can attach a Meal Marker to your 
blood sugar result when the Meal Marker feature in the meter is 
turned On. This feature lets you track your blood sugar levels over 
time with separate Target Ranges for Fasting, Before Meal, and 
After Meal markers.
Your CONTOUR NEXT ONE meter comes with Meal Markers turned 
Off. You can turn Meal Markers On in Settings.
Turn Meal Markers On
To turn Meal Markers On see Settings: Set Meal Markers on page 41.
NOTE: You can select a Meal Marker only when the blood sugar 
test result displays on the screen.
If the Target Light (smartLIGHT) setting is On, the test strip port 
displays a color representing your result value compared to the 
Before Meal, After Meal, or Overall Target Range.
In Target  Below Target  Above Target 
If your blood sugar result is below target, the Target Light 
(smartLIGHT) is red and meter beeps twice.
If you do not select a Meal Marker, your blood sugar test result is 
compared to an Overall Target Range.

LO or HI Results
•  If the meter beeps twice and 
displays the LO screen, your 
blood sugar reading is under 
20 mg/dL. Follow medical advice 
immediately. Contact your health 
care professional.
•  If the meter beeps once and 
displays the HI screen, your blood 
sugar reading is over 600 mg/dL:
1. Wash and dry your hands well.
2. Retest with a new strip. 
If results are still over 
600 mg/dL, follow medical 
advice immediately.
Alternative Site Testing (AST): Palm
WARNING
•  Ask your health care professional if Alternative Site Testing 
(AST) is right for you.
•  Do not calibrate a continuous glucose monitoring device 
from an AST result.
•  Do not calculate an insulin dose based on an AST result.
Always wash your hands with soap and water and dry them well 
before and after testing or handling the meter, lancing device, or 
test strips.
Test Results
WARNING
•  Always consult your health care professional before 
changing your medication based on test results.
•  If your blood sugar reading is under 50 mg/dL, follow 
medical advice immediately.
•  If your blood sugar reading is over 250 mg/dL:
1. Wash and dry your hands well.
2. Retest with a new strip.
If you get a similar result, call your health care professional as 
soon as possible.
Expected Test Result Values
Blood sugar values will vary depending on food intake, medication 
dosages, health, stress, or activity. Nondiabetic plasma glucose 
concentrations should be less than 110 mg/dL in the fasting state 
and less than 140 mg/dL in the post-prandial state (after a meal).6 
Youshould consult with your health care professional for glucose 
values specific to your needs.

Get a Blood Drop: Alternative Site Testing
1. Wash your hands and the puncture 
site with soap and warm water.
Rinse and dry well.
2. Attach the clear AST endcap to 
the lancing device, if provided with 
your kit.
Refer to the lancing device 
insert for detailed instructions.
3. Select a puncture site from a 
fleshy area on the palm. Avoid 
veins, moles, bones, and tendons.
The lancing device graphics are for illustration purposes only.
4. Press the lancing device firmly 
against puncture site, then press 
the release button.
5. Maintain steady pressure until a 
small, round blood drop forms.
For Alternative Site Testing, use the clear endcap. Your 
CONTOUR NEXT ONE meter can be used for fingertip or palm testing. 
See the lancing device insert for detailed instructions on Alternative 
Site Testing.
Do not use AST under the following conditions:
•  If you think your blood sugar is low.
•  When blood sugar is changing rapidly, such as after a meal, after an 
insulin dose, or during or after exercise.
•  If you are unable to feel symptoms of low blood sugar 
(hypoglycemic unawareness).
•  If you get alternative site blood sugar results that do not agree with 
how you feel.
•  During illness or times of stress.
•  If you will be driving a car or operating machinery.
Alternative site results may be different from fingertip results when 
glucose levels are changing rapidly (e.g., after a meal, after taking 
insulin, or during or after exercise). Additionally, glucose levels may 
not rise as high or fall as low as levels in the fingertip. As such, 
fingertip results may identify hypoglycemic levels sooner than 
alternative site results.
Alternative Site Testing is recommended only when it is more than 
2 hours after a meal, diabetes medication, or exercise.
If you do not have a clear lancing device endcap to perform AST, 
contact Diabetes Care Customer Service. See the back cover for 
contact information.

6. Lift the lancing device straight up 
and away from the skin without 
smearing the blood.
7. Test immediately after you have 
formed a small, round blood drop, 
as shown.
Immediately touch the tip of the 
test strip to the drop of blood. The 
blood is drawn into the test strip 
through the tip.
Do not test the blood sample from palm if you get:
•  Smeared blood.
•  Clotted blood.
•  Runny blood.
•  Clear fluid mixed with the blood.
8. Hold the tip of the test strip in the blood drop until the meter beeps.
CAUTION: Do not press the test strip tip against the skin or place 
the blood on top of the test strip. These actions could lead to 
inaccurate results or errors.
Apply More Blood for Alternative Site Testing
1. If the meter beeps twice and the 
screen displays a blinking blood 
drop, the test strip does not have 
enough blood.
2. Apply more blood to the test strip 
within 60 seconds.
3. If the screen displays an E 1 error 
message, remove the strip and 
start with a new strip.
If the Meal Marker feature is On, the meter suggests a Fasting , 
Before Meal , After Meal  , or No Mark   marker for your blood 
sugar result. This is based on the time of day and the meal period: 
fasting/breakfast, lunch, dinner or overnight. The Meal Marker is 
blinking.

Principles of the Procedure: The CONTOUR NEXT 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 CONTOUR NEXT ONE system is 
designedfor 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).7
