Important Information About Your New Meter
• Your new meter is designed and approved for testing fresh capillary whole blood samples (for
example, blood from your fingertip or forearm). The meter is for outside the body (in vitro) use.
It should not be used to diagnose diabetes.
• This meter requires Accu-Chek Aviva Test Strips. Other test strips may give inaccurate results.
• Your new meter comes with a preset time and date. You may need to change the time to your
time zone.
• If you have followed the steps in the booklet, but still have symptoms that do not seem to
match your test results—or if you have questions—talk to your healthcare professional.

Chapter 2: Testing Your Blood Glucose
Performing a Blood Glucose Test
Before you perform your first blood test, set up your meter correctly. You need the meter, a test
strip, and a lancet device with a drum loaded.
1. Prepare your lancet device.
4. Make sure the code number on the display
matches the code number on the test strip
container. If you miss seeing the code
number, remove the test strip and reinsert
it into the meter.
2. Wash and dry your hands.
3. Insert a test strip into the meter in the
direction of the arrow. The meter turns on.

Flagging Test Results
If you wish, you can “flag” your test result with an asterisk ( ) to mark a special result. You might
want to flag an event such as an AST result or exercise. When you review your results in memory,
this “flag” can help you remember what was different about the result.
Here is how to flag a result:
1. Perform a test.
2. With the test result on the display, and the test strip STILL IN THE METER,
press

Alternative Site Testing (AST)
You have the option of testing other places on your body besides the fingertip. You can test the palm,
forearm, upper arm, thigh, or calf. While fingertip blood can be tested at any time during the day, there
are times when testing from any other approved site is not ideal—usually when your blood glucose is
rapidly changing. Please read the following section before you try testing from other places.
IMPORTANT
•
Talk to your healthcare professional about Alternative Site Testing.
!
▲
Chapter 2
Do not change your treatment because of just one result.
NEVER ignore symptoms of high or low blood glucose.
If your blood glucose does not match how you feel, perform a fingertip test to
confirm your result. If the fingertip result still does not match how you feel, call
your healthcare professional.
18
Alternative site testing may be done:
• Immediately before a meal
• Fasting
DO NOT test from an alternative site:
• Two hours or less after eating
• After exercising
• If you are sick
• If you think your blood glucose is low
• If you often don’t notice when your blood glucose is low
• When basal insulin is most active
• After injecting rapid-acting insulin (two hours or less)

Unusual Test Results
If your blood glucose result does not match the way you feel, follow these steps:
Troubleshooting Checks
Action
1. Check the expiry date of the test strips.
If it is past the expiry date, discard the test strips.
2. Ensure that the cap on the test strip container is
always closed tightly.
If you think it may have been uncapped for some time,
replace the test strips.
3. Check if the test strip was out of the container for
a long time.
Repeat the test with a new test strip.
4. Check that your test strips were stored in a cool,
dry place.
Repeat the test with properly stored test strips.
5. Check that you followed the testing steps.
Read Chapter 2 “Testing Your Blood Glucose” and test
again. If you still have problems, call Roche Diagnostics.
6. Check that the code number on the meter
display matches the code number on the test
strip container.
If they do not match, insert the correct code chip in
the meter and test again.
7. If you are still unsure of the problem…
repeat the test with a new test strip. If you still have
problems, call Roche Diagnostics.

Symptoms of High or Low Blood Glucose
Being aware of the symptoms of high or low blood glucose can help you understand your test
results and decide what to do if they seem unusual. Here are the most common symptoms:
High blood glucose (hyperglycemia): fatigue, increased appetite or thirst, frequent urination, blurred
vision, headache, or general aching.
Low blood glucose (hypoglycemia): sweating, trembling, blurred vision, rapid heartbeat, tingling, or
numbness around mouth or fingertips.

If you are experiencing any of these symptoms, test your blood glucose.
If your blood glucose result is displayed as LO or HI, contact your healthcare
professional immediately.

Chapter 3: Meter Memory, Setup,
and Downloading
Memory
Storing Test Results
Your meter automatically stores up to 500 test results with the time and date of the test. You
can review them at any time. Test results are stored from the newest to the oldest, so it is very
important to have the correct time and date set in the meter.
Notes:
• Do not change your therapy based on one individual result in memory.
• The memory is not lost when you replace the battery. You do need to check that the time and
date are correct. See Chapter 1 “Adjusting the Time and Date.”
• Once 500 results are in memory, adding a new result causes the oldest one to be deleted.
• Hold
or
down to scroll through the results faster.
• The control results do not appear in memory. They are not included in the 7, 14, and 30 day
averages.

Chapter 4: Control Testing
Why Perform Control Tests
Performing a control test lets you know that your meter and test strips are working properly to give
reliable results. You should perform a control test when:
•
•
•
•
You open a new box of test strips
You left the test strip container open
You want to check the meter and test strips
Your test strips were stored in extreme
temperatures
• You dropped the meter
• Your test result does not agree with how
you feel
• You want to check if you are testing
correctly
About the Control Solutions
• Only use Accu-Chek Aviva Control Solutions.
• Your meter automatically recognizes the
control solution.
• Write the date you opened the bottle on the
bottle label. The solution is good for three
months from that date or until the expiry date
on the bottle label, whichever comes first.
• Do not use control solution that is past the
expiry date.
• The solution can stain clothing. If you spill it,
wash your clothes with soap and water.
• Close the bottle tightly after use.
• Store the bottle at 2 to 32°C. Do not freeze.
43
Performing a Control Test
You need the meter, a test strip, and control solution Level 1 or Level 2.
The control level is printed on the bottle label.
OR
1. Insert a test strip into the
meter in the direction of
the arrow. The meter
turns on.
Chapter 4
2. Make sure the code number
on the display matches the
code number on the test
strip container. If you miss
seeing the code number,
take the test strip out and
reinsert it into the meter.
44
3. Select the control solution
you want to test. You will
enter the level later in the
test.
4. Put the meter on a flat surface, like a
table.
Chapter 4
5. Remove the control bottle cap. Wipe the
tip of the bottle with a tissue.

Example
The label on your test strip container shows the
acceptable ranges for both the Level 1 and the
Level 2 control solutions. The result you get
should be inside this range. Make sure you
compare the result to the correct level of control.
Chapter 4
When the control result is inside the range on
the test strip container, your test strips and
your meter are working properly.
48
If your control result is not inside the acceptable range, here are some things you can do to solve the problem:
Troubleshooting Checks
Action
1. Check the expiry date of the test strips and
control solution.
If either is past the expiry date, discard it. If the control solution was opened more than three months ago, discard it.
2. Check that you wiped the tip of the control solution bottle
before and after use.
Wipe the tip of the bottle with a tissue. Repeat the control
test with a new test strip and a fresh drop of control solution.
3. Ensure that the caps on the test strip container and the
control solution bottle are always closed tightly.
If you think either may have been uncapped for some time,
replace the test strips or control solution.
4. Check if the test strip was out of the container for a long
time.
Repeat the control test with a new test strip.
5. Check that your test strips and control solutions were
stored in a cool, dry place.
Repeat the control test with properly stored test strips or
control solution.
6. Check that you followed the testing steps.
Read Chapter 4 “Control Testing” and test again. If you still
have problems, call Roche Diagnostics.
7. Check that you chose the correct control solution level,
either 1 or 2, when you performed the test.
If you chose the wrong control solution level, you can still
compare the control result to the range printed on the test
strip container.
8. Check that the code number on the meter display
matches the code number on the test strip container.
If they do not match, insert the correct code chip in the
meter and test again.
9. If you are still unsure of the problem…
repeat the control test with a new test strip. If you still
have problems, call Roche Diagnostics.

Measuring Principle
The enzyme on the test strip, glucose dehydrogenase, in the presence of the coenzyme (PQQ),
converts the glucose in the blood sample to gluconolactone. This reaction creates a harmless DC
electrical current that your meter interprets for your blood glucose. The sample and environmental
conditions are also evaluated using a small AC signal.
Blood glucose concentrations may be measured in whole blood or plasma. Although you always
apply whole blood to the test strip, your meter displays blood glucose results that relate either to
whole blood or plasma. To see whether your blood glucose meter displays results relating to whole
blood or plasma, see the package insert that came with your test strips. You will also find information on how the system works, on the test principle and on reference methods.

Information for Healthcare Professionals
!

Healthcare Professionals: Follow the infection control procedures appropriate
for your facility.
Decisions about whether to recommend alternative site testing (AST) should take into account the
motivation and knowledge level of the patient and his or her ability to understand the considerations
relative to diabetes and AST. If you are considering recommending AST for your patients, you need
to understand that there is a potential for a significant difference between fingertip and alternative
site blood glucose test results. The difference in capillary bed concentration and blood perfusion
throughout the body can lead to sample site-to-site differences in glucose results. These
physiological effects vary between individuals and can vary within a single individual based upon
his or her behavior and relative physical condition. Our studies involving alternative site testing of
adults with diabetes show that most persons will find their glucose level changes more quickly in
the fingers’ blood than the alternative sites’ blood. This is especially important when glucose levels
are falling or rising rapidly. If your patient is used to making treatment decisions based upon
fingerstick readings, he or she should consider the delay, or lag-time, affecting the reading
obtained from an alternative site.
