1. About This Manual
The purpose of the Coag-Sense PT/INR Monitoring System
User’s Manual is to help you understand your Coag-Sense
system, its parts, and its intended function. It provides you with
the information you need to perform PT/INR testing with the
Coag-Sense system.
It is important to read this entire User Manual and inserts that
came with the disposable Coag-Sense test strips. You must
complete proper training on the Coag-Sense system and
practice the test with a health care provider before attempting to
use this device. The Coag-Sense system should only be used
with a doctor’s prescription.
This User Manual has different formats and symbols to
distinguish warnings, notes, and meter buttons.
WARNING: This indicates a warning or precaution.
Please read and understand all warnings and precautions.
They tell you about potential safety hazards and situations
that may cause injury. If you have any questions, please
ask your doctor or contact Technical Support (USA) at
1-866-903-0890.
Note ◙:Notes provide additional information that is useful or
important. All notes are italicized. Words in BOLD ALL-
CAPITALS refer to buttons on the Coag-Sense meter.

2. System Description
The Coag-Sense Self-Test PT/INR Monitoring System is used
for measurement of Prothrombin Time (PT) in fresh, capillary
whole blood. The Coag-Sense system is intended for use
outside the body by people taking warfarin or other oral
anticoagulant (blood thinning) therapy who need to monitor
clotting time.
The meter performs a self-test when it is first turned on. If there
are any problems with the meter, an error message is shown on
the display. Refer to the “Troubleshooting” section of this manual
or contact Tech Support. A test strip is inserted and heated in the
meter prior to sample application.
The strip contains a tiny wheel with spokes that pull the sample
into the reaction well. The spokes quickly and completely mix the
sample with the clot initiating component of the test strip.
The PT time is determined from when (a) the sample is drawn
into the reaction well of the test strip and detected by a beam of
light until (b) a clot forms and interrupts a beam of light. The PT
result is converted to an INR (International Normalized Ratio)
using the calibration data stored in the meter. INR is a
mathematical correction of the PT result that adjusts for
sensitivity differences among different PT systems.
The meter continues to check every feature of its operation
through a system of self-checks.

4. Warnings and Precautions
General
Patients taking Warfarin (Coumadin) and other oral
blood thinners should consult with their healthcare
provider before adjusting their dosage.
Patients should consult with their doctor for the
appropriate INR therapeutic range for them.
Patients who have recently taken or are currently taking
any type of Heparin or Low Molecular Weight Heparin
anticoagulant should not use this test system and should
consult their doctor.
Test Site and Blood Sample
The quality of the blood sample can become the
weakest link in any PT test. A blood sample of poor
quality can produce results of poor quality. Read the

Warnings and Precautions
CoaguSense, Inc. For In Vitro Diagnostic Use Page 11
section on “Collecting a Fingerstick Sample” for more
information.
Use only fresh fingerstick capillary blood for testing. The
blood should only come in contact with the products
provided with the Coag-Sense System. Other products
may have anti-coagulant agents on their surfaces and
result in unreliable test results.
The Coag-Sense PT/INR System is for in vitro diagnostic
use only.
Blood samples must be applied to the test strip
immediately after collection or the blood begins to
clot, causing unreliable results.
Squeezing the fingerstick site excessively (milking)
releases “tissue layer” fluid and tissue factors that can
cause unreliable results.
The fingerstick site should be washed with warm water
and soap, and then completely dried. The site must be
clean of all hand oils/lotions and foreign matter, which
may cause unreliable results.
If Alcohol wipes are used, wipe the fingerstick site with a
gauze pad and make sure the site is completely dry. If
any alcohol remains (or is re-introduced) on the finger, it
may cause unreliable results.
The quality of fingerstick and the sample delivered are
important to the test results. If there is a question
about the sample or sample collection, obtain a new
strip, repeat the fingerstick on a different finger, and
test again.
If a test requires a repeat, use a different finger for the
fingerstick, since blood may have started to clot on the
first finger, which may cause unreliable results.

Coag-Sense®Prothrombin Time (PT)/INR Monitoring System Self-Test User’s Manual
Page 12 For In Vitro Diagnostic Use CoaguSense, Inc.
If there is a bubble or an air pocket showing in the blood
sample in the transfer tube, start the test over. Use a
new strip and fingerstick (using a different finger and
transfer tube) or results may be unreliable.
Note ◙:If you are unable to get a PT/ INR test result contact
Technical Support at 1-866-903-0890, your home testing
service provider or your healthcare provider.

9. Performing a Control Test
Control testing confirms the performance of both the meter and
the test strips and should be completed for each new lot of test
strips and any other time as indicated by your testing service
provider or doctor. Control testing can also be run whenever the
PT results are unexpected to make sure that the system is
working properly. There are 2 low control strips, 2 high control
strips and a control strip activation solution shipped with each
test strip kit. Extra controls may be ordered separately.
Follow these steps to perform a test on a low or high control.
Note ◙:The following directions are for running a low control
strip. When this procedure is complete, run a high
control strip. The controls may be run in any order. The
meter will display and store the results in PT seconds
only. The meter does not use or require results from the
control strips prior to running a patient test strip.
WARNING: Do not move or touch the meter while it
is running a test. Unreliable results may occur.
Note ◙:If an error message appears, consult the
“Troubleshooting” section of this manual.
