The CoaguChek XS Plus System
The CoaguChek XS Plus System measures blood-clotting time (prothrombin time) for
people who are taking anticoagulation medications, such as Coumadin®or warfarin. The
CoaguChek XS Plus System measures blood-clotting time using blood from the fingertip or
whole blood from a vein (nonanticoagulated venous whole blood).
The CoaguChek XS Plus System quantitatively measures prothrombin (blood-clotting) time
(PT/Quick value/INR). INR is a measure of the rate at which blood clots. A low INR can
increase the risk of blood clots, while a high INR can increase the risk for internal bleeding.
The patient’s physician will determine the best INR range for that patient, depending on why
the patient is taking anticoagulants and how the patient reacts to them. The doctor will also
determine how often the patient needs blood testing.
The system includes the CoaguChek XS Plus meter and CoaguChek XS PT test strips.
Optional liquid CoaguChek XS Plus PT Controls are also available. The meter guides you
through the test step by step using the symbols and instructions on the display. Each box of
test strips has its own code chip that you insert into the meter. This code chip contains lot-
specific information about its test strips, such as the expiration date and calibration data.
The CoaguChek XS Plus System makes coagulation testing easy. You only need to insert
the code chip, turn the meter on, insert the test strip, and apply a blood sample. The blood
mixes with the ingredients on the test strip, and the meter determines when the blood is
clotted. The meter displays the result in about one minute. After the measurement, the
meter automatically stores the results in memory so you can easily recall them. The patient’s
physician will use these results to successfully treat the patient’s condition.
The CoaguChek XS Plus System also includes data management with security features, such
as the QC (quality control) lockout for use with optional liquid quality controls.
If you need technical help, call Roche Diagnostics Technical Service Center
at 1-800-428-4674, 24 hours a day, 7 days a week, 365 days a year.
Introduction
Introduction
Please note: Before you use the meter for the first time (after you have first 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.

Test principle
The CoaguChek XS PT Test, used as directed with the CoaguChek XS Plus Meter, will
provide an electrochemical measurement of prothrombin time following activation of blood
coagulation with human recombinant thromboplastin. In simple terms, blood works with the
chemicals in the test strip to make a small electric current in the test strip that measures
blood-clotting time.

Safety Information
The CoaguChek XS Plus System
9
Protection against infection
Medical staff using the CoaguChek XS Plus System to perform tests on
patients must be aware that any contact with human blood is a potential
source of infection.
nUse gloves.
nUse a separate lancet and lancing device for each person.
nDispose of used lancets and test strips in a sturdy sharps container
with a lid.
nFollow all health and safety regulations applicable to your laboratory
or practice.

Operating conditions
To be sure that your CoaguChek XS Plus System functions properly, please observe the
following guidelines:
nOnly use the meter at a room temperature between 59°F and 90°F (15°C and 32°C).
nOnly use the meter at a relative humidity between 10 and 85 percent.
nWhen operating the meter using the power adapter, use only a voltage of 100 V to
240 V (± 10%), 50/60 Hz.
nA touch screen makes the meter easier to operate. To use the touch screen, simply use
your finger (even when wearing gloves) or special pens designed for use with handheld
devices to select a screen prompt. Pointed or sharp objects can damage the touch screen.
Touch lightly, holding until the prompt is selected.
nWhen testing, place the meter on a level, vibration-free surface, or hold it so it is roughly
horizontal.
Introduction

Electromagnetic interference
Do not use the meter near strong electromagnetic fields, which could interfere
with the proper operation of the meter.

Quality control
The CoaguChek XS Plus System has a number of built-in quality-control functions.
nA check of the electronic components and functions every time the meter is turned on.
nA check of the test strip temperature while a test is in progress.
nA check of the expiration date and lot information on the test strip carried out by the
code chip.
nA two-level, on-board quality control test and patient result determination within a single
test chamber.
Roche Diagnostics has available optional liquid quality controls for the CoaguChek XS Plus
System. These controls are provided to assist with regulatory compliance requirements as
applicable to your facility.

Power supply
The CoaguChek XS Plus meter can operate with either the power adapter provided, batteries,
or a special rechargeable battery pack (REF 04805640001). The CoaguChek XS Plus System
uses four AA batteries. The batteries should last for about 60 tests, depending on the type of
battery used. You should insert the batteries or optional rechargeable battery pack even when
you use the power adapter. This ensures that you will not lose the date and time settings if
the power goes out.
To save power, the CoaguChek XS Plus meter has the option to automatically turn itself off
based on your setup selections, unless a screen prompt has been pressed or a new test strip
has been inserted. The default setting is set to OFF. When the meter turns itself off, all results
obtained up to that point remain in memory and the settings will still be there when you
power the meter back on. (Refer to Auto off in the chapter entitled Options setup.)
During battery operation, the meter always
displays the battery power level.
The meter retains results in memory even when no batteries are inserted. All other settings,
other than date and time after 10 minutes, are retained as well.

When replacing the batteries, you must
insert the new batteries within 10 minutes
of removing the old ones, to keep the
date and time settings. If you take longer
than this, you may need to re-enter the
date and time. To make sure that you
do not lose your date and time settings,
connect the power adapter while you
change the batteries.

Before using the meter for the first time, carry out the following steps:
1Insert batteries* and/or connect the power adapter.
2Set the current date and time.
3Enter the settings of choice (language, unit of measure, user administration if applicable, etc.).
* Instead of batteries, you can use a special rechargeable battery pack. If you choose this
option, order the pack separately from Roche Diagnostics. To recharge, connect the power
adapter to the CoaguChek XS Plus meter.

Meter setup
You can call up any displayed function by
touching the screen prompt for it with your
finger (or a special pen for this purpose).
Touch the screen lightly, holding until the
prompt is selected.
If the meter did not automatically enter the
SETUP mode (e.g., after the batteries were
replaced), you can call up the SETUP menu
from the main menu.
The following screen prompts are used in the
Setup menus:
nSCREEN for changing the way the
display looks
nOPTIONS for setting SORT, BEEPER,
AUTO OFF, and COMPUTER options
nID SETUP for user management and
patient management options
nLOCKOUTS for optional liquid quality
control options
Meter setup
1 Touch the SETUP screen prompt to
call up the meter settings.
2 Select the group of settings of choice.
Please note: If you have not set the date and time (after turning the meter on for
the first time or because the batteries were removed from the meter for more than
10 minutes), you cannot perform a test. In that case, turning on the meter takes you
immediately to the Setup mode, where you must set the date and time.
Once the date and time are set, the meter automatically moves to the main menu, where
you can start a test or enter more settings. The next time you turn the meter on, the date
and time will remain and you will automatically go to the main menu.
