Expected Results for people without diabetes:
3
Plasma Blood Glucose Result
Before eating
< 110 mg/dL
Two hours after meals
< 140 mg/dL
A Doctor or Diabetes Healthcare Professional determines personal target glucose ranges.
If you are having symptoms that suggest your glucose is too low or too high, contact your Doctor or
Diabetes Healthcare Professional right away.
If comparing results using TRUE FOCUS Test Strips to laboratory test results, perform a fingerstick
blood test within 30 minutes of the laboratory test. If you have eaten recently, results using TRUE
FOCUS Test Strips can be up to 70 mg/dL higher than venous laboratory results.
4
Diabetes experts
have suggested that glucose meters should agree within 15 mg/dL of a laboratory method when
the glucose concentration is less than 75 mg/dL, and within 20% of a laboratory method when the
glucose concentration is 75 mg/dL or higher.
5
Troubleshooting
If your result is unusually high or low or doesn’t match the way you feel, perform a Control Solution
Test (see
Quality Control Testing
).
If the Control Test is within range:
• Read
Blood Glucose Testing
again.
• Recheck your results with a new TRUE FOCUS Test Strip.
If the results are not within range:
• Check the Use by Dates. Do not use if past either written date or date printed on test strip vial or
control solution bottle, whichever comes first. Test with new test strips/control solution.
• Check for error messages. If an error message appears, follow the Actions in the Message
Section of the Owner’s Booklet.
• Check your testing technique. Perform another Control Test.
If the results still do not match the way you feel, check with your Doctor or Diabetes Healthcare
Professional before changing your treatment program.

Blood Glucose Test Strips
Instructions for Use
Quality Control (QC) Testing
There are two quality control tests to let you know that the blood glucose monitoring system is
working properly.
Automatic Self-Test
An Automatic Self-Test is performed each time a TRUE FOCUS Test Strip is inserted into a TRUE
FOCUS Meter. Upon inserting a test strip into the Test Port, if all segments appear and the Drop
Symbol appears in the Display, the meter is working properly.
Control Test
TRUE FOCUS Control Solution is used to check testing technique and blood glucose monitoring
system performance. When Control Test results fall within ranges found on test strip vial label
of test strips being used, the blood glucose monitoring system is working properly and testing
technique is good.
Important Information:
It is important to perform Control Tests with more than one level of control
solution to assure your blood glucose monitoring system is working properly and your testing
technique is good. There are three levels of TRUE FOCUS Control Solution available that contain
known amounts of glucose. For more information on obtaining different levels of control solution,
call 1-800-803-6025, Monday - Friday, 8AM-8PM EST.
See TRUE FOCUS Control Solution Instructions for Use or TRUE FOCUS Owner’s Booklet for more
information on Quality Control Testing.
Blood Glucose Testing
1. Check opened date and printed date on test strip vial label. Do not use if after either date
printed on the test strip vial label or 90 days after date opened, whichever comes first.
2. Allow meter and test strips to sit at room temperature for 10 minutes. If opening vial for the
first time, write date opened on vial label.
3. Wash area to be lanced, dry.
4. Remove one test strip from vial. Recap vial right away.
5. Insert Contact End of test strip into Test Port of meter. Meter turns on. Do not remove test strip
from meter until testing is finished.
6. Obtain blood drop.
7. With test strip still in meter, touch Sample Tip to top of blood drop and allow blood to be drawn
into test strip. Remove Sample Tip from drop immediately after the meter begins to count down
from 4.
If meter does not begin testing 5 seconds after touching test strip to blood drop, see
Troubleshooting
in the TRUE FOCUS Owner’s Booklet.
8. Result is displayed. Record result.
9. Hold meter with test strip pointing down. Press Strip Release Button to discard test strip into
appropriate container.
WARNING!
Upon opening the test strip carton, examine the product for missing, damaged or broken parts.
Ensure the test strip vial cap is securely closed. If the product is damaged or the vial cap is not
closed, DO NOT use the test strips for testing; product may give inaccurate results. Contact Trividia
Health Customer Care at 1-800-803-6025 for replacement and assistance.
Caring for Test Strips
• Test strips must be kept in original vial with vial cap tightly sealed. NEVER transfer test strips
from one vial to another.
• Write date opened on test strip vial label when removing the first test strip. Discard all unused
test strips in vial after either date printed on the test strip vial label or 90 days after date
opened, whichever comes first. Using test strips past these dates may cause inaccurate results.
• Store test strip vial in a dry place at room temperature between 59°F-86°F and at 10% - 90%
Relative Humidity.
DO NOT REFRIGERATE OR FREEZE.
Do not store in bathroom or kitchen.
Do not expose to extreme heat or cold, direct sunlight or high humidity for any length of time.
• Discard any test strips or vials that appear damaged.
• Do not bend, cut, or alter test strips in any way.
Important Information
• Use TRUE FOCUS Test Strips only with TRUE FOCUS Meters and TRUE FOCUS Control Solution.
Using other meters or controls may give inaccurate results.
• Test strips are for in vitro testing only. Do not consume.
• Meter and lancing device is for self-testing and intended for use on one person ONLY. Do not
share your meter or lancing device.
• Use fresh, capillary whole blood from fingertip or forearm. Do not use venous blood for testing.
• Check with your Doctor or Healthcare Professional to see if forearm testing is right for you.
Results from forearm are not always the same as results from fingertip.
• Alternative site testing should not be used to calibrate continuous blood glucose monitors
(CGMs). Alternative site testing should not be used for insulin dose calculations.
• Use fingertip instead of forearm for more accurate results:
1
- Within 2 hours of eating, exercise, or taking insulin,
- If your blood sugar may be rising or falling rapidly or your routine results are often fluctuating,
- If you are ill or under stress,
- If your forearm test results do not match how you feel,
- If your blood sugar may be low or high,
- If you do not notice symptoms when blood sugar is low or high.
• NEVER use serum, plasma, or clotted blood for testing.
WARNING!
•
NEVER
reuse test strips.
NEVER
wipe test strips with water, alcohol or any cleaner.
DO NOT
attempt to remove blood or control solution from test strips or clean test strips and re-use.
Reuse of test strips will cause inaccurate results.
• Use test strip quickly after removing from vial. Recap vial right away. Test strips left outside of
vial too long give an error message.
•
NEVER
add a second drop of sample to test strip. Adding more sample gives an error message.
• Discard used test strips and lancets into an appropriate container. Contact with blood presents
an infection risk.
• Do not change treatment plan based on the results from the System without the advice of your
Doctor or Diabetes Healthcare Professional.
• Do not use on neonates (newborns).
Cleaning and Disinfecting
• The TRUE FOCUS Blood Glucose Monitoring System is for one person use
ONLY. DO NOT
share
your meter or lancing device with anyone, including family members.
• All parts of the blood glucose monitoring system can potentially transmit infectious diseases
from bloodborne pathogens, even after cleaning and disinfecting.
2
• Cleaning and disinfecting the lancing device and the meter destroys most, but not necessarily
all, blood-borne pathogens.
• Wash your hands thoroughly with soap and warm water before and after handling the meter,
lancing device, lancets, or test strips as contact with blood presents an infection risk.
• If the meter is being operated by a second person who provides testing assistance, the meter
and lancing device should be disinfected prior to use by the second person.
• It is important to keep the meter and the lancing device clean and disinfected. For instructions
on how to clean and disinfect the meter and lancing device, see
Meter Cleaning and Disinfecting
and
Lancing Device Cleaning and Disinfecting
in the Owner’s Booklet.

Limitations
6
• Therapeutic levels of n-acetlycysteine and elevated uric acid may affect results. Cholesterol up to
500 mg/dL or triglyceride up to 750 mg/dL does not significantly affect results.
The following will not affect accurate results:
6
• Testing at altitudes up to and including 10,000 feet.
• Hematocrit levels between 25% and 60%.
DO NOT perform capillary blood glucose testing on critically ill patients.
Capillary blood glucose
levels in critically ill patients with reduced peripheral blood flow may not reflect the true physiological
state. Reduced peripheral blood flow may result from the following conditions (for example):
7
• shock
• severe hypotension
• severe dehydration
• hyperglycemia with hyperosmolarity, with or without ketosis.

Intended Use
TRUE FOCUS Blood Glucose Test Strips are used only with TRUE FOCUS Meters to quantitatively
measure whole blood glucose in fresh, human capillary whole blood taken from the fingertip or
forearm. The TRUE FOCUS Blood Glucose Monitoring System is intended to be used by a single
person and not shared.
The blood glucose monitoring system is intended for self-testing at home (over-the-counter).
Testing is performed outside the body (
in vitro
diagnostic use) by a single person with diabetes as
an aid for monitoring the effectiveness of diabetes control. The blood glucose monitoring system
is not to be used on neonates or for the diagnosis or screening of diabetes mellitus. Alternative site
(forearm) testing can only be performed during steady-state blood glucose conditions.
Test Principle
The TRUE FOCUS Test Strip is a plastic strip containing chemicals and electrodes. When inserted into
a TRUE FOCUS Meter, glucose is measured using amperometric technology employing a glucose
dehydrogenase-FAD reaction. When whole blood or TRUE FOCUS Control Solution is drawn into
the Sample Tip of the test strip, glucose in the sample reacts with the chemicals and produces an
electrical current. The meter measures the current and calculates the amount of glucose. The result
is displayed as a plasma value.
Chemical Composition
Glucose dehydrogenase-FAD
(Aspergillus sp.)
, mediators, buffers and stabilizers.
