Expected Results for people without diabetes:
3
Plasma Blood Glucose Result
Before eating
< 100 mg/dL
2 hours after a meal
< 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 METRIX,TRUE METRIX AIR and TRUE METRIX GO Self Monitoring Blood
Glucose Systems to laboratory test results, perform a fingerstick blood test within 30 minutes of the
laboratory test. If you have eaten recently, results using TRUE METRIX,TRUE METRIX AIR and TRUE METRIX
GO Self Monitoring Blood Glucose Systems can be up to 70 mg/dL higher than venous laboratory results.
4
Troubleshooting
If your result is unusually high or low or doesn’t match the way you feel, perform a Control Test
(see
Quality Control Testing
).
If the Control Test is within range:
• Read
Blood Glucose Testing
again.
• Recheck your results with a new TRUE METRIX Self Monitoring Blood Glucose 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 next to
EXP
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 TRUE METRIX, TRUE METRIX AIR or TRUE METRIX GO Self Monitoring Blood
Glucose System 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.

Self Monitoring Blood Glucose Test Strips
Instructions for Use
Intended Use
TRUE METRIX® Self Monitoring Blood Glucose Test Strips are to be used with TRUE METRIX, TRUE
METRIX AIR and TRUE METRIX GO Self Monitoring Blood Glucose Meters to quantitatively measure
whole blood glucose in fresh, human capillary whole blood taken from the fingertip.
The TRUE
METRIX and TRUE METRIX AIR meters are indicated for forearm testing. TRUE METRIX GO
meter is not indicated for forearm testing.
TRUE METRIX Self Monitoring Blood Glucose Test
Strips, used with the TRUE METRIX, TRUE METRIX AIR and TRUE METRIX GO Self Monitoring Blood
Glucose Meters, are intended to be used by a single person and not shared. The TRUE METRIX Self
Monitoring Blood Glucose Test Strips are intended to be used with the TRUE METRIX, TRUE METRIX
AIR and TRUE METRIX GO Self Monitoring Blood Glucose Meters 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. TRUE METRIX Self
Monitoring Blood Glucose Test Strips, with the TRUE METRIX, TRUE METRIX AIR and TRUE METRIX
GO Self Monitoring Blood Glucose Meters, should not to be used on neonates or for the diagnosis or
screening of diabetes mellitus. Alternative site testing can only be performed during steady-state
blood glucose conditions (when glucose is not changing rapidly).
Test Principle
The TRUE METRIX Self Monitoring Blood Glucose Test Strip is a plastic strip containing chemicals
and electrodes. When inserted into a TRUE METRIX, TRUE METRIX AIR or a TRUE METRIX GO Self
Monitoring Blood Glucose Meter, glucose is measured using amperometric technology employing a
glucose dehydrogenase-FAD reaction. When whole blood or TRUE METRIX 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, detects and corrects for hematocrit and
temperature, and calculates the glucose result. The result is displayed as a plasma value.
Chemical Composition
Glucose dehydrogenase-FAD
(Aspergillus species)
, mediators, buffers and stabilizers.
Quality Control (QC) Testing
There are two quality control tests to let you know that the System is working properly.
Quality Control Test: Automatic Self-Test
An Automatic Self-Test is performed each time a TRUE METRIX Self Monitoring Blood Glucose Test
Strip is inserted into a TRUE METRIX, TRUE METRIX AIR or TRUE METRIX GO Self Monitoring Blood
Glucose 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.
Quality Control Test: Control Test
TRUE METRIX Control Solution is used to check testing technique and System performance. When
Control Test results fall within ranges found on test strip vial label of test strips being used, 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 System is working properly and your testing technique is good. There are
three levels of TRUE METRIX Control Solution available that contain known amounts of glucose.
For more information on obtaining different levels of control solution, call 1-800-803-6025 or
1-954-677-4599 for assistance, Monday - Friday, 8AM-8PM EST.
See TRUE METRIX Control Solution Instructions for Use or TRUE METRIX, TRUE METRIX AIR or TRUE
METRIX GO Self Monitoring Blood Glucose System Owner’s Booklet for more information on the
frequency of 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 4 months after date opened, whichever comes first.
Discard vial and test with new vial.
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 beeps and dashes
appear across meter display.
If meter does not begin testing 5 seconds after touching test strip to blood drop, see
Troubleshooting
in the TRUE METRIX, TRUE METRIX AIR or TRUE METRIX GO Self Monitoring
Blood Glucose System Owner’s Booklet.

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 next to
EXP
on the test strip vial label or 4 months 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 a temperature between 40°F-86°F at 10%-80% relative
humidity.
DO NOT 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 METRIX Self Monitoring Blood Glucose Test Strips only with TRUE METRIX, TRUE
METRIX AIR and TRUE METRIX GO Self Monitoring Blood Glucose Meters and TRUE METRIX
Control Solution. Using other meters or controls may give inaccurate results.
• Test strips are for
in vitro
diagnostic use 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 Diabetes Healthcare Professional to see if forearm testing* is right for
you. Results from forearm* are not always the same as results from finger.
• 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 finger 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.
* The TRUE METRIX and TRUE METRIX AIR meters are indicated for forearm testing.
TRUE METRIX GO meter is not indicated for forearm 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.
Cleaning and Disinfecting
• TRUE METRIX Self Monitoring Blood Glucose Test Strips, with the TRUE METRIX, TRUE METRIX AIR and TRUE
METRIX GO Self Monitoring Blood Glucose Meters, are for one person use
ONLY. DO NOT
share your meter or
lancing device with anyone, including family members.
• All parts of the System (meter, test strips, control solution, lancing device and lancets) 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 blood or cleaning solution gets into the test strip vial, discard vial and use a new vial for testing. Using test
strips that may have become contaminated may result in incorrect results or error messages if used for testing.
• If you have any liquids on your hands, especially blood, make sure you clean and completely dry your hands
before opening the test strip vial.
• If the meter is being operated by a second person who provides testing assistance, the meter and lancing
device should be cleaned and 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 TRUE METRIX, TRUE METRIX AIR or TRUE METRIX GO Self Monitoring System Owner’s Booklet.
Limitations
5
• Do not use during xylose absorption testing, as xylose may produce falsely elevated glucose
results during a xylose absorption test for diagnostic evaluation of malabsorption. Please check
with your Doctor before using the TRUE METRIX, TRUE METRIX AIR or the TRUE METRIX GO Self
Monitoring Blood Glucose System.
• Ascorbic acid (Vitamin C) greater than normal or therapeutic levels may cause significant
interference resulting in inaccurate result.
• It is known that uric acid can interfere with this device at normal and disease levels, when uric
acid concentrations are greater than 5 mg/dL. For people with diabetes, certain conditions may
cause your blood level of uric acid to rise. These conditions include gout or kidney disease, this
means you may have significant interference resulting in inaccurate glucose results and your
blood glucose results may be not reliable. Please check with your Doctor or Diabetes Healthcare
Professional before using the TRUE METRIX, TRUE METRIX AIR or the TRUE METRIX GO Self
Monitoring Blood Glucose System.
• Testing at altitudes greater than 10,200 ft may cause inaccurate results.
• Hematocrit levels below 20% or above 70% may cause inaccurate results.
• Critically ill patients should not be tested with this device.
• Inaccurate results may occur in severely hypotensive individuals or in dehydrated patients or
patients in shock. Inaccurate results may occur for individuals experiencing a hyperglycemic-
hyperosmolar state, with or without ketosis.
• The TRUE METRIX, TRUE METRIX AIR or TRUE METRIX GO Self Monitoring Blood Glucose Systems
have not been tested with animals. Do not use to test blood glucose on pets.
