The Coag-Sense® PT2 Prothrombin Time (PT)/INR Monitoring
System
Intended Use
The Coag-Sense PT2 Prothrombin Time (PT)/INR Monitoring
System is an in vitro diagnostic device that provides quantitative
prothrombin time (PT) results, expressed in seconds and INR
units. It uses fresh capillary whole blood. It is intended for use by
health care professionals at the point of care to monitor patients
who are on warfarin-type (coumarin) anticoagulation therapy. The
device is not intended to be used for screening purposes.
The Coag-Sense PT2 Professional PT/INR Monitoring System
may be used for multiple-patient testing in a professional
healthcare setting.
Anticoagulation Medication
Oral anticoagulation medications, are typically prescribed to
patients to avoid unwanted clots. The patient’s blood clotting time
must be monitored to ensure that their dosage is correct.
Oral anti-coagulation medication is prescribed to patients with
acute and chronic conditions including, but not limited to:
congestive heart failure, atrial fibrillation, prosthetic heart valve,
myocardial infarction, joint replacement, deep vein thrombosis,
pulmonary embolism, thrombotic stroke, coronary artery disease,
venous thromboembolism and cancer.
Blood-clotting Time
The rate at which blood clots is measured in units is called
International Normalized Ratio (INR). It is very important for
patients to stay within their individual target INR range. If the INR
is too low, the risk of blood clots increases. If the INR is too high,
Page 4 For In Vitro Diagnostic Use CoaguSense, Inc.
the risk of hemorrhaging increases. The patient’s physician will
determine the most appropriate INR range for the patient,
depending upon the patient’s indication and how they respond to
the oral anticoagulant.

2. System Description
The Coag-Sense PT2 Professional Prothrombin Time (PT)/INR
System is used for quantitative measurement of Prothrombin
Time (PT) in fresh, capillary whole blood. The Coag-Sense PT2
Professional PT/INR system is intended for use outside the body
(in vitro diagnostic use) to test patients taking warfarin-type 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 Technical 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 the 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 series of self-checks.

4. Warnings and Precautions
CoaguSense, Inc. For In Vitro Diagnostic Use Page 13
Test Site and Blood Sample
The Coag-Sense PT2 Professional PT/INR monitoring
system is for in vitro diagnostic use only.
The Coag-Sense meter will not produce a result if the test
strip is past its expiration date.
The quality of the blood sample can affect PT test results.
A blood sample of poor quality can produce unreliable
results. Read the section on “Collecting a Fingerstick
Sample” for more information.
Blood samples must be applied to the test strip
immediately after collection or the blood begins to clot,
causing unreliable results.
The blood sample transferred to the test strip must be a
minimum of 10 µL in volume. Low sample volume may
cause an error message.
Use only fresh fingerstick capillary blood for testing. The
blood should only come in contact with the products
provided with the Coag-Sense PT/INR system. Other
products may have anti-coagulant agents on their
surfaces and result in unreliable test results.
Squeezing the fingerstick site excessively (milking)
releases interstitial “tissue layer” fluid that can cause
unreliable results.
The fingerstick site can 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 Isopropyl Alcohol (IPA) wipes are used, wipe the
fingerstick site with a gauze pad and make sure the site is
Page 14 For In Vitro Diagnostic Use CoaguSense, Inc.
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 delivery
technique 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 you need to repeat a test, use a different finger for the
fingerstick, since blood may have started to clot on the
first finger, which may cause unreliable results.
If there is a bubble or an air pocket showing in the blood
sample in the collection tube, start the test over. Use a
new fingerstick (using a different finger and collection
tube) or results may be unreliable.
Refer to the package inserts provided with the Lancets
and Sample Transfer Tubes for more information.

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. 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. If multiple boxes
of test strips are purchased at the same time and they
have the same lot number, only one low and one high
control from that lot needs to be tested.
Note◙: If an error message appears, consult the
“Troubleshooting” section of this manual.

WARNING: Unexpected results
An unexpected result may include any result that falls outside
the patient’s therapeutic target range, or a result that falls
inside the target range but is not consistent with the patient’s
current health status (e.g., patient is experiencing bleeding or
bruising).
What can cause unexpected results:
Certain prescription drugs (for example, heparin) and certain
over-the-counter medications (for example, antibiotics) can
affect the action of oral blood thinners and the INR value.
Changes in diet, lifestyle, or taking nutritional supplements
such as ginkgo biloba can affect the action of oral blood
thinners and the INR value. Liver diseases, congestive heart
failure, thyroid dysfunction, Lupus, antiphospholipid antibody
syndrome (APS) and other diseases or conditions can affect
the action of oral blood thinners and the INR value.
Be sure to confirm whether the patient has any of these
conditions before you begin testing, and any time there are
changes in health patient status or medications after you have
begun testing.
What to do when you get an unexpected result:
Follow instructions for re-testing on the Coag-Sense PT/INR
meter. For unexpected results, contact Technical Support at
1-866-903-0890
. Consider re-testing using an alternative
method prior to adjusting the patient’s dose of anticoagulant
medication, or any other corrective actions.

Sample Transfer Tubes
Sterile alcohol prep pads
Gauze square
Band-Aids
Biohazard waste container (SHARPS)
For fingerstick blood testing, increasing the flow of blood
in the finger will help you capture a good drop
of blood. Before you prick the finger, have the patient
warm their hand by washing it in warm water, holding it
under their armpit, or by using a hand warmer. Ensure
that the patient’s hand is dry prior to testing.
Do not use fingers with tight rings, scars, calluses, or
other features that prevent getting good access to the
blood.
One of the middle or index fingers on either hand
is recommended.
Gently squeeze or massage the finger to be lanced, near
the tip. Good circulation can be seen if the patient’s
fingertip changes to a pinkish shade.
Use a 21g 1.8 mm depth single-use auto-disabling lancet.
CoaguSense, Inc. For In Vitro Diagnostic Use Page 35
23g lancets) should not be used.
Refer to the Lancet
device instructions for more information on use.
Lance the fleshy part of the fingertip just slightly left or
right of the center.
Press lancet firmly against finger.
For better blood flow, you may have the patient hold their
hand below their heart.
Squeeze the finger from the
sides to open up the wound for proper blood flow if
necessary to produce pea sized drop.
The best test sample is when:
The blood is collected right after the fingerstick and put
into the sample well without delay. If there is any delay in
sample collection or application, repeat with a fresh
fingerstick and a new strip.
There are no bubbles or air pockets in the tube or sample.
WARNING:
Patient samples, controls, used test strips,
transfer tubes and lancets are potentially infectious. Dispose
of strips and collection devices using universal precautions.

12. Reviewing the Memory
The Coag-Sense PT2 Professional meter stores up to 100 results,
along with the date and time in its memory. When the 100th result
is reached, the first result 1 is replaced (written over) with test
results for test number 101. This continues with the oldest result
being replaced with the most recent. Memory is not lost if there is
a break in power for any length of time. Memory cannot be erased.

14. Control Strips
Quality control is an important part of PT testing to verify the
integrity of the performance characteristics of the testing system.
The Coag-Sense Meter has been designed with multiple internal
systems to ensure proper system function. When turned on, the
meter runs an extensive self-check protocol to assure, for
example, that room temperature, timing functions, optical and
mechanical functions are within specification. There are 2 low
control strips, 2 high control strips and a control strip activation
solution shipped with each test strip kit. Each control strip
contains plasma of known INR. Real plasma allows for a fully
functional liquid quality control test of both the reagents’ ability to
generate a clot and the analyzer’s ability to detect a clot. Control
testing confirms the performance of both the meter and test strips
and should be completed for each new lot of test strips.
15. Rechargeable Lithium Battery
Description and statements to be added.
CoaguSense, Inc. For In Vitro Diagnostic Use Page 43
16. Cleaning and Disinfecting the Meter
No maintenance is required other than routine cleaning and/or
disinfecting. To clean the outside of the meter use a clean damp
non-abrasive cloth.
If instructions for use are properly followed, patients should not
come in direct contact with the Coag-Sense PT2 Professional
meter thereby reducing the possible transmission of bloodborne
pathogens between patients. Sample should always be
transferred from the patient to the meter using a new disposable
sample transfer tube.
The meter housing can be disinfected using a 10% bleach
solution (EPA reg. No. 5813-50) or 70% isopropyl alcohol. Apply
the disinfecting product to a lint-free cloth and wipe the meter for
a minimum contact time of 2 minutes. Alcohol prep pads may also
be used.
Placementonwhereto
cleanoutsidemeter
The test strip is designed to contain the patient sample,
preventing it from entering the meter. Do not clean/disinfect
inside the meter where the test strip is inserted, cleaning this area
Page 44 For In Vitro Diagnostic Use CoaguSense, Inc.
should be avoided. Please call Technical Support at
1-866-903-0890 if this area requires cleaning/disinfecting.
After disinfecting the meter, gloves should be removed and hands
washed before proceeding to the next patient.
Please call Technical Support at 1-866-903-0890 with any
cleaning or disinfecting questions.
WARNING:
Do not put the meter in liquid. Do not
allow liquids to get inside the meter or into any of the
connectors or plugs on the meter. If you suspect any
physical damage or deterioration of the meter (such as
cracking or gross distortion), or if the meter does not turn on
after cleaning, call Technical Support.
Always refer to local, state and federal disinfecting guidelines.
More information on bloodborne pathogen safety and proper
disinfecting techniques can be found at:
