Intended use
Introduction
The CoaguChek
INR (International Normalized Ratio) based
on a prothrombin time (PT) response to
monitor the effect of a therapy with vitamin
K antagonists by using the CoaguChek XS
PT Test strips. The CoaguChek Vantus System
uses fresh capillary whole blood from a nger
stick.
The system is intended for properly selected
and suitable trained users on the prescription
of the treating doctor.
Users should be stabilized on anticoagulation
with vitamin K antagonists for at least 6 weeks
prior to single patient self-testing with the
CoaguChek Vantus System.
The CoaguChek Vantus System is intended
for single patient self-testing only for adults,
age 22 years and older.

PT time
Self-testing
Introduction
A PT test is often called an INR test. The
International Normalized Ratio (INR) is a way
of standardizing the results of prothrombin
time tests because there are different test
methods. INR enables you and your doctor
to understand your coagulation results even
when they come from different labs using
different test methods.
If you self-test, you need to discuss your
therapy model with your healthcare
professional rst. Self-testing is not a
substitute for regular visits to your doctor.
Depending on the training you have received
and the instructions from your healthcare
professional, you might communicate your
results to a healthcare professional or clinic
toreceive the appropriate dose adjustment.
CoaguChek Vantus User’s Manual, version 1.0
Self-monitoring of oral anti coagulation
therapy using coagulation values
determined with the CoaguChek Vantus
System may only be undertaken after
consultation with your doctor and
comprehensive instruction by a qualied
healthcare professional.
This manual contains all the information
you need to operate and care for the
CoaguChek Vantus System. Please read
this entire manual carefully before you
use the meter.

The CoaguChek Vantus System
Introduction
The CoaguChek Vantus System makes
coagulation testing easy. The graphical user
interface of the CoaguChek Vantus meter
guides you through the test step by step.
The code chip accompanying the test strips
contains strip lot-specic information and the
expiry date for the test strips. You only need
to insert the code chip, turn the meter on,
insert the test strip, and apply a blood sample.
The CoaguChek Vantus meter measures your
coagulation time and displays the result. After
the test is completed, the meter automatically
saves the result to memory.
CoaguChek Vantus User’s Manual, version 1.0
If you have any questions about the CoaguChek
Vantus meter, please contact CoaguChek
Technical Services at 1-800-428-4674. You
will nd further contact details on page 146.
Please note: Before you use the meter
for the rst time (i.e. after you have rst
inserted the batteries), you must set the
date and time correctly to allow you to carry
out measurements properly. Each time you
replace the batteries, you need to check
(and, if necessary, adjust) the date and
time.
Note on screenshots:
The test results and software and hardware
information shown in the screenshots in
this manual are for illustration purposes
only. The information displayed on your
meter may differ.

Test principle
Introduction
The CoaguChek XS PT Test test strip
contains a lyophilized reagent (reagent
in dried form). The reactive components
of this reagent consist of thromboplastin
and a peptide substrate. When a sample is
applied, thromboplastin activates coagulation,
which leads to the formation of thrombin.
At the same time, the meter starts to
measure the time. The enzyme thrombin
cleaves the peptide substrate, generating an
electrochemical signal. Depending on the
time elapsed when it rst appears, this signal
is then converted by means of an algorithm
into an INR result.

Operating conditions
Introduction
To ensure that your CoaguChek Vantus
System functions properly, please observe the
following guidelines:
• Only use the meter at a temperature
between 59 °F and 90 °F.
• Only use the meter at a relative humidity
between 10% and 85%.
• When testing, place the meter on a level,
vibration-free surface or hold it so that it is
roughly horizontal.
• If the meter is to remain unused for a
longer period of time, keep it in the carrycase supplied.
• Use the meter only up to a maximum
altitude of 13120 feet.
Electromagnetic interference
Strong electromagnetic elds may interfere
with the proper operation of the meter. Do not
use the meter near strong electromagnetic
elds.
CoaguChek Vantus User’s Manual, version 1.0
Quality control
The CoaguChek Vantus System has a number
of built-in quality control functions such as:
A check of the electronic components and
functions every time the meter is turned on.
A check of the test strip temperature while a
test is in progress.
A check of the expiry date and lot information
on the test strip.
A quality control function is incorporated into
the test strip. These on-board quality control
checks verify the test strip integrity.

To save power, the CoaguChek Vantus meter
automatically turns itself off after 2 minutes
unless a button has been pressed or a new
test strip has been inserted. When the meter
turns itself off, all results obtained up to that
point remain in memory.
When the Main Menu screen is displayed,
the meter indicates the battery power level
on the top right of the display. The battery
symbol is divided into four segments which
correspond to the battery power level.
Replace batteries at latest when the ashing
red battery symbol or a corresponding

Please be aware that battery life may be
affected by many factors, such as battery
type, quality, operating conditions (e.g.
ambient temperature), frequency of use,
and test duration.

Introduction
CoaguChek Vantus User’s Manual, version 1.0
The meter retains all data in the memory, even
when no batteries are inserted. This includes,
in particular, your test results and all settings.
However, if the meter is without batteries for
more than 30 minutes, the current time (clock
time) and date may be lost. In this case, you
might have to re-enter the time and date
manually.
Think of the environment. Dispose of used
batteries sensibly.
WARNING
Do not throw batteries onto a re. They may
explode!

Inserting the batteries
Starting Up
When replacing the batteries, you should
insert the new batteries within 30 minutes
of removing the old ones, to keep the date
and time settings. If you take longer, you
may have to re-enter the date and time.
Only use alkaline batteries 1.5V type AAA
1
(LR03).
With normal use, the batteries will last for
approximately 60 tests.
Roche recommends replacing used batteries
only with new high quality batteries and not
mixing different brands. Do not mix new
and already used batteries.
Think of the environment. Dispose of used
batteries sensibly.

Use of rechargeable batteries is not
recommended. If you do use rechargeable
batteries, the following may happen:
• The number of tests that can be
performed per battery charge is much
lower than with alkaline batteries.
• Performing tests in a cold environment
may not be possible.
• The capacity remaining may not be
displayed correctly. If the meter displays
a Battery Low message, performing
further tests may be impossible. Replace
the batteries as soon as possible.
