follow their advice on treatment.
1
If you continue to get unexpected
results, check your system with control solution. If you are experiencing
symptoms that are not consistent with your blood glucose test results
AND you have followed all instructions described in your User’s
Handbook, call your health care professional. Never ignore symptoms or
make signicant changes to your diabetes control programme without
speaking to your health care professional.
Checking the System
Use only OneTouch® Vita™ Control Solutions
A control solution test is performed to check that the meter and test
strips are working together properly and that you are performing the
test correctly. For instructions on how and when to check the system
by performing a control solution test, refer to the User’s Handbook that
came with your system.
Limitations of the Procedure
OneTouch® Vita™ Test Strips give accurate results when the following
restrictions are observed:
• Do not use for the diagnosis of diabetes or for testing newborn
babies.
• Teststripsareforsingleuseonly.Do not re-use.
• TheteststripsarespecictoD-glucoseanddonotreactwithother
sugars that may be present in blood.
• Useonlyfreshcapillarywholeblood.Do not use serum or plasma.
• Haematocritisthepercentageofredbloodcellsintheblood.
Extremes in haematocrit may aect test results.

Haematocrit levels
below 30% may cause falsely high readings and haematocrit levels
over 55% may cause falsely low readings. If you do not know your
haematocrit level, consult your health care professional.

Health care professionals—please note these additional procedural
restrictions:

anticoagulants or preservatives.
• Interferences:Paracetamol,salicylates,uricacid,ascorbicacid
(vitamin C), and other reducing substances (when occurring in normal
blood or normal therapeutic concentrations) do not signicantly
aect results. However, abnormally high concentrations in blood may
cause inaccurately high results.

not been tested and are not recommended for testing with the
OneTouch® Vita™ Meter.
Test Principle
The OneTouch® Vita™ system is plasma-calibrated to allow easy
comparison of results with laboratory methods. Glucose in the
blood sample mixes with special chemicals on the test strip and a
small electrical current is produced. This current is measured by the
OneTouch® Vita™ Meter and displayed as your blood glucose result.
The strength of this current changes with the amount of glucose in
the blood sample.
Reagent Composition
Each test strip contains: Glucose oxidase (Aspergillus niger) ≥0.08IU;
ferricyanide ≥22µg;otheringredients(buer,etc.).Theteststripvial
contains a drying agent.
Performance Characteristics
The performance of OneTouch® Vita™ Test Strips has been evaluated
both in laboratory and in clinical tests.

IMPORTANT: Please read this information and your OneTouch®
Vita™ User’s Handbook before using OneTouch® Vita™ Test Strips.
Do not use your OneTouch® Vita™ Test Strips if your vial is open
or damaged in any way as this could lead to error messages

1800 535 676 (Ireland) immediately if the test strip vial is open or
damaged, or if these instructions or your meter results seem unclear.
Intended Use
OneTouch® Vita™ Test Strips are used with the OneTouch® Vita™ meter
for quantitatively measuring glucose in fresh capillary whole blood.
OneTouch® Vita™ Test Strips and meter are for use in ngertip, palm,

Blood Glucose Test Procedure
For instructions on performing a blood test (including blood sample
collection) and the range of expected blood glucose values, refer to the
User’s Handbook that came with your system.
Test Results
TheOneTouch®Vita™Meterdisplaysresultsbetween1.1–33.3mmol/L
(20and600mg/dL).RefertotheUser’sHandbookfortherangeof
expected blood glucose values.
Low Glucose Values
Ifyourtestresultisbelow1.1mmol/L(20mg/dL),awarningmessage
will appear indicating a low glucose level. This may indicate severe
hypoglycaemia (low blood glucose). Treat this condition immediately,
according to your health care professional’s recommendations.
Although this message could be due to a test error, it is safer to treat rst
and then do another test.
High Glucose Values
Ifyourtestresultisabove33.3mmol/L(600mg/dL),awarningmessage
will appear indicating a high glucose level. This may indicate severe
hyperglycaemia (high blood glucose). You should re-test your glucose
level. If the message appears again, call your health care professional
immediately.
If You Get Unexpected Results
