INTENDED USE

The ProTime Microcoagulation System is a portable, battery-operated instrument with a disposable cuvette

for quantitative determination of prothrombin time from fingerstick whole blood or anticoagulant-free

venous whole blood. The product is intended for use in the management of patients treated with oral

anticoagulants by a healthcare professional and for patient self-testing. Additional information for medical

professionals to monitor patients is located at the end of this instruction manual. Materials are available

through ITC for professionals to train patient self-testers using the ProTime Microcoagulation System.

ProTime instruments intended for patient self-testing are available in the U.S. by prescription only. These

instruments include patient-specific product instructions.

For in vitro Diagnostic Use.

SUMMARY AND EXPLANATION

What Does The ProTime Microcoagulation System Do?

The ProTime Microcoagulation System is designed for testing prothrombin time (PT) and International

Normalized Ratio (INR). The reagents for a prothrombin time test are in the cuvette. Whole blood clotting

time is converted to INR, than the result is calculated for plasma equivalent PT seconds. This test is done to

check the status of patients receiving oral anticoagulation therapy.

What is INR?

The International Normalized Ratio (INR) was developed to help the doctor compare an individual’s

prothrombin time results from one lab to another. An advantage of reporting an INR is to allow for

normalization of comparisons from one lab or instrument to another. The precision of the INR is improved

when a reagent with a lower ISI is used.

Note: ISI stands for International Sensitivity Index. ProTime uses this number to calculate PT

seconds from INR.

Blood Coagulation Test Methodology

Traditional coagulation tests measure the time required for the formation of a fibrin clot following the

addition of a coagulation-activating reagent. Laboratory assays typically use plasma recovered from

anticoagulated (citrated) whole blood samples. The clotting time is a measure of the functionality of the

patient’s hemostatic system. Specific coagulation activating reagents are employed in various clotting tests to

measure specific components of the hemostasis system. Clotting times are prolonged in the case of either

decreased procoagulant activity or increased anticoagulant activity.

Summary of the Blood Coagulation System

The events leading to the formation of a fibrin clot are simplified in coagulation theory into two coagulation

pathways: the intrinsic and the extrinsic pathways. There are twelve clotting factors or proteins involved in

this cascade scheme, numbered I through XIII (excluding VI). The prothrombin time test measures the

extrinsic coagulation pathway and is sensitive to coagulation Factors VII, X, V, II and Fibrinogen (I). With the

exception of Factor V, vitamin K is a required co-factor for biosynthesis of these factors in the liver. The

prothrombin time (PT) test uses thromboplastin as the active reagent to initiate the extrinsic pathway. The

prothrombin time test will be prolonged in patients with liver disease or vitamin K deficiency. The test is

widely used to monitor oral anticoagulant therapy that suppresses the synthesis of vitamin K-dependent

clotting factors.

PRINCIPLES OF OPERATION

The ProTime Microcoagulation System measures the PT using fibrin clot formation and detection. The

ProTime cuvette is a self-contained, micro volume reaction cell constructed of precision-molded plastic.

There are two user options within the ProTime Microcoagulation System: the standard ProTime cuvette and

the ProTime3 cuvette. These cuvettes differ from each other in the amount of blood that needs to be

collected and tested.

The standard ProTime cuvette has five micro-channels, which contain the dried reagents required to

perform triplicate testing of the PT assay and two levels of controls. The ProTime3 cuvette has three

functional micro-channels. Two micro-channels perform the controls, and one micro-channel performs the

PT test. The standard ProTime uses the Tenderlett Plus device for performing the fingerstick, and it is

designed to hold 65 µL of blood (approximately 3 drops) needed to fill all five micro-channels. The

ProTime3 uses the Tenderlett Plus LV (low volume) device for performing the fingerstick, and it collects 27

µL of blood (approximately 1 large drop) needed to fill the three micro-channels of the ProTime3 cuvette.

The instrument draws the precise volume of blood into the micro-channels of each cuvette, which contain

thromboplastin and other reagents. An array of LEDs detects the motion of sample/reagent mixtures as they

move through a precision restriction in each channel. The blood is pumped back and forth until a clot

forms, obstructing the channel and slowing the flow of blood. The instrument detects the clot when the

blood movement decreases below a predetermined rate.

SAFETY FEATURES AND QUALITY CONTROL

Each ProTime and ProTime3 cuvette has two channels for performing the two levels of control which work

simultaneous with the channel(s) used for testing the PT assay. The built-in safety features of the

instrument and integral reagent controls work together to ensure that the instrument and reagent systems

are working properly and that the test procedure was performed correctly. Two levels of quality control are

performed with each and every test.

Calibration

The ProTime instrument and cuvettes are pre-calibrated. No additional calibration is required.

Reagents

ProTime cuvettes are pre-loaded with dried thromboplastin, stabilizers and buffers. The thromboplastin

has a high sensitivity, measured as an ISI near 1.0. Each cuvette performs the prothrombin time test and,

in addition, has one channel for a Level I control and one channel for a Level II control. The controls

consist of purified plasma-extracted coagulation factors and anticoagulants.

Operating Precautions

• For in vitro Diagnostic Use.

• The ProTime instrument is designed for use only with ProTime cuvettes.

• The ProTime instrument will not perform a test if the cuvette is past its expiration date or has been

improperly stored.

• The ProTime instrument is designed to be used for testing in a stationary position. DO NOT perform

testing while carrying or holding the instrument.

• In order to charge the ProTime instrument, the AC power cord should be plugged into an electrical

service outlet and the AC/DC power module while the DC power cord from the AC/DC power module is

plugged into the DC port in the back of the ProTime instrument.

• DO NOT expose the ProTime instrument to extreme temperature (above 35°C, 95°F). Such exposure

could affect the performance of any type of electronic instrumentation.

• DO NOT drop the ProTime instrument, and do not use the results if the instrument is dropped during

a test.

• DO NOT attempt to open the ProTime instrument other than for battery replacement, as there are no

user-serviceable parts.

• DO NOT remove the AC/DC power module from the ProTime instrument by pulling on the cord.

Patient specimens and used cuvettes are potentially infectious. The cuvettes include materials that have

been prepared from human plasma or serum that has been tested using US FDA recognized methods and

found to be non-reactive for HIV antibody and for hepatitis B surface antigen. Handle with appropriate care and

dispose of cuvettes and blood collection materials in accordance with standard methods of biohazard control.

The use of accessory equipment (e.g., printers, etc.) not identified in this manual either in the patient

vicinity, or that does not comply with either the equivalent safety requirements of this equipment or

UL/IEC 60601-1 or IEC 60601-1-2, may lead to a reduced level of safety with the resulting system.

Limitations

• The ProTime instrument uses only fresh capillary or venous whole blood. Plasma or serum cannot be

used. Glass tubes or syringes must not be used to collect venous samples. Use only plastic syringes

without anticoagulants to collect venous samples. Poor fingerstick blood collection technique may

affect results.

• In clinical trials, no significant difference was observed between fingerstick and venous specimens run

on ProTime. During those trials, ProTime measured patients with an INR range of 0.8 to 7.0.

ProTime is programmed to calculate and report INR results as follows:

If the calculated INR is:

< 0.6

0.6 - 0.79

0.8 - 7.0

7.1 - 9.9

10.0 - 12.0

> 12.0

Then ProTime displays:

INR LOW

INR < 0.8

Result

Result - followed by "*"

INR > 9.9

INR HIGH

•

Results may be affected in patients receiving supra-therapeutic heparin or who have an abnormal

response to heparin.

• Correlation of results reported by the ProTime instrument to laboratory results depends on the precision

of the laboratory method and on the ISI value of the laboratory reagent and instrument system.

• Do not disturb instrument while test is in progress.

As with all diagnostic tests, ProTime Microcoagulation System test results should be scrutinized in light of a

specific patient’s condition and anticoagulant therapy. Any results exhibiting inconsistency with the

patient’s clinical status should be repeated or supplemented with additional test data.

Follow doctor’s instructions if you have difficulty performing the test or receive a result outside of the

prescribed therapeutic range.

Rechargeable Battery Facts

• Batteries discharge naturally over time (approximately 5% per month).

• Battery capacity (the amount of charge the battery will hold) is lower at low temperatures.

• Batteries that are charged to their maximum capacity will generate heat if they continue to be charged.

• The ProTime instrument uses a rechargeable NiMH (Nickel Metal Hydride) type battery. The maximum

capacity of any rechargeable battery will gradually decrease over time. To ensure maximum life of the

rechargeable battery, read and follow the information in Care of the ProTime Battery for Maximum

Life section.

Care of the ProTime Battery for Maximum Life

A new instrument, an instrument that is used infrequently, or an instrument with a new replacement

battery, should be plugged in for at least 8 hours before use to ensure that the battery is completely charged.

The instrument screen will show CHARGING BATTERY when the AC/DC power module is connected to the

AC power cord and the ProTime instrument. The screen will show CHARGE COMPLETE when the battery is

fully charged. The AC/DC power module should be disconnected after the CHARGE COMPLETE message is

seen. The AC/DC power module that has been supplied by ITC has been selected specifically for use with

your ProTime Microcoagulation System. Do not use any other AC/DC power module.

When the battery indicator on the screen shows less than 25% charge remaining, please refer to the

Charging the Battery section for instructions. To maximize battery life, allow your ProTime instrument to

discharge completely before re-charging. Avoid charging the ProTime instrument for frequent, short

periods of time (such as charging for a few minutes, removing from the AC/DC power module, and then

recharging again). Avoid storing and charging the ProTime instrument at extreme temperatures.

Built-in ProTime Battery Features

Insert the cuvette into the slot with the printing face up and the bar-code down.

The WARMING screen will appear as follows:

10

Page 11

3.

Prepare for Finger Incision

While the cuvette is warming, prepare the finger. Wait for the prompt before incising the finger

and collecting blood.

It is easier to collect blood if the hands are warm. Follow these steps to ensure a good sample:

• Wash the hands in warm water or rub hands together to stimulate blood flow.

• Apply firm pressure to the palm and finger. Massage the hand and push blood into the

fingertips.

• Cleanse middle or ring finger and dry. To prevent contamination, do not touch the site after

cleansing.

4.

Blood Collection

When this screen appears, it is time for the finger incision.

CAUTION: Blood collection must be finished within 2:10 minutes to prevent early

clotting of the sample. ProTime will keep time. If the 2:10 minute interval has expired

and the button has not been pressed during this interval, a TIME OUT error message

is displayed. To run another test, repeat procedure from Step 2.

• Place the Tenderlett Plus device firmly against the side of the finger. Place thumb on top of

the device as shown, and press the red trigger firmly using the other thumb.

•

•

Wipe away the first trace of blood.

Gently massage from the base of the finger to force blood to the tip so that a large drop of

blood forms.

11

Page 12

5.

•

Touch the large drop of blood to the collection cup. Keep adding blood until the blood level

fills the cup above the line.

•

For Tenderlett Plus LV, ensure the cup is filled completely. Ensure the blood extends all

the way to the bottom of the cup. Add another drop if you are not sure you have

enough.

Snap Tenderlett Plus to ProTime

• Hold the device at an angle and place the front end of the device into the slot in the

instrument.

• Press down to click the Tenderlett Plus in place. You should hear a soft click.

Note: Proper engagement of the

Tenderlett Plus to the cuvette is

critical to prevent a sample error.

6.

cuvette.

12

Page 13

•

It takes only a few seconds for ProTime to draw the blood into the cuvette. Watch the

screen for the next prompt.

7. Remove Tenderlett Plus

Remove Tenderlett Plus immediately when prompted to do so.

CAUTION: Failure to do so will result in an error message. ProTime allows you six

seconds.

•

•

Do not press the button after the Tenderlett Plus is removed from the ProTime

instrument while you are testing your INR. This will interrupt the test procedure, and you

will have to start over with a new blood sample.

The instrument then progresses to the test and displays the TESTING screen.

• The result remains displayed for 5 minutes or until the button or the button is pressed.

• If the cuvette has not been removed and the instrument is left unattended for 5 minutes, the

instrument will display the following messages before shutting down and powering OFF:

What Does the Result Mean?

The result indicates the clotting activity of blood. When ProTime is used as a self-testing instrument, the

healthcare provider may program ProTime with the upper and lower limits that are right for the patient. In

this case, ProTime will display OTR if results are outside of the therapeutic range. The OTR will not display

if results are within the limits. If no limits are set, ProTime will display only the result.

Note: If OTR (Out of Therapeutic Range) appears after the INR result, the result is out of the

therapeutic range (TR) limits that have been preset by the professional (see the For

Professionals Only – Program Mode section).

TROUBLESHOOTING

Most often, an error message indicates a problem with blood collection or a mistake in the test procedure. If

an error message appears, read the instructions again and repeat the test with a new cuvette. The

Troubleshooting Guide section gives the messages for the most common errors with possible causes and

solutions.

As with all diagnostic tests, the ProTime Microcoagulation System test results should be scrutinized in light

of a specific patient’s condition and anticoagulant therapy. Any results exhibiting inconsistency with the

patient’s clinical status should be repeated or supplemented with additional test data.

If you get a persistent error, write down the error message and call ITC Technical Support at

1-732-548-5700, 1-800-631-5945, or e-mail us at techsupport@itcmed.com.
