INRatio2 monitor ~ overview
HemoSense has developed a product that challenges current PT (Prothrombin Time) testing alternatives with innovation, cost reductions, ease of use and reliability. The INRatio system consists of a low-cost monitor and disposable test strips that can be used by patients at home or medical professionals in a clinic to quickly and accurately perform the PT test.
The INRatio2 monitor represents the latest from HemoSense in PT/INR testing at home. The INRatio brand is the #1 selling PT/INR point of care monitor for 5 years in a row (according to HPIS data 2005-2009). INRatio2 allows you to obtain your Prothrombin Time (PT) and International Normalized Ratio (INR) results in less than a minute using 1 drop of blood from a fingerstick.
The INRatio2 system allows you to self-test your PT/INR more often without having to travel to a lab. It reduces the headache of oral anticoagulation management, is easy to use, and features on-board quality controls with every test.

How it Works
A Test Strip is inserted into the INRatio2 monitor.
A drop of fresh whole blood from a fingerstick is applied to the test strip.
The blood is drawn into the test area by capillary action where it mixes with reagents that cause coagulation to begin.
The monitor performs the PT test AND 2 quality control tests (normal and therapeutic) simultaneously, and determines whether the controls are within preset limits. If they are, strip integrity is verified, and the monitor reports the PT test result. If they are not, the monitor displays an ERROR message.
The test results are displayed in less than 60 seconds.

INRatio2 monitor ~ The INRatio® Test Strip
Compatibility
The Test Strip is compatible with both the INRatio and the INRatio2 monitor.
Unique Electrochemical Technology
The test strip is made of laminated layers of transparent plastic. The simple design features a sample well where blood is applied, 3 channels through which the blood sample flows to reach the testing areas, reagents to start the coagulation process, and electrodes that interface with the monitor.
Built-In Quality Controls
The monitor uses the test strip's 3 channel technology to perform the PT test AND 2 quality control tests (normal and therapuetic) simultaneously, and determines whether the controls are within preset limits. If they are, strip integrity is verified, and the monitor reports the PT test result. If they are not, the monitor displays an ERROR message. The unique technology of the INRatio strip performs the Quality Control test alongside the actual test sample, requiring no additional steps.
Individually Wrapped
Each Test Strip is individually wrapped in a foil pouch, offering protection from heat and humidity, and minimizing exposure to the environment.
No Refrigeration Required
Test Strips can be stored at room temperature until they expire, saving refrigerator storage space, and allowing more testing flexibility for patients when traveling.
INRatio2 monitor ~ Patient Prothrombin Time Self Testing
Just as blood glucose self-testing has revolutionized the management of diabetes, self-testing for Prothrombin Time has the potential to provide a positive impact on patient therapeutic outcomes.
Benefits of Patient Self-Testing:
More frequent testing gives more data points to monitor INR
Fewer trips to clinic/lab for patients
Waiting time for results is reduced to about 2 minutes
Physicians can make immediate dosage adjustments
Reduction in phone calls to lab and patient with test results
Overall time to manage therapy is reduced
Patient geographic freedom is increased
Patient involvement/understanding of therapy is increased
How Is Self-Testing Implemented?
Physician selects patients capable of home self-testing
Physician writes a prescription for INRatio
Distributor/IDTF assists patient with proper paperwork, including reimbursement
Patient receives INRatio, and is trained by Distributor/IDTF
Patient begins home testing on schedule set by physician
Patient phones in test results to Distributor/IDTF's computerized reporting system
Physician reviews patient's test results via computerized system, and makes dosage changes if necessary
Physician continues to manage the patient's therapy
INRatio2 monitor ~ PT / INR Point of Care (POC) Testing
Challenges in Traditional Clinic/Lab PT Testing
Traditional PT testing involves performing the PT/INR test at a clinic or lab, with multiple steps for both patient and professional. The age and condition of the typical oral anticoagulation patient make traditional testing challenges clear:
Many patients must drive to a clinic or lab
Long wait time for test results: 45 mins - 1 hour
Only medical personnel can perform the test
Complex multi-step testing procedure
Time-consuming management of patient therapy
As technology improves, PT testing is migrating from traditional labs to Point of Care sites such as clinics, physician offices, and even the patient's home, yet certain shortcomings still exist, such as in the area of quality control.
Challenges in Quality Control for Current Point of Care Testing Devices
Since erroneous or inaccurate PT results can have a damaging effect on patients, it is essential that the device passes quality control tests to confirm the reliability and accuracy of the test. Existing devices require some or all of the following from the patient or medical professional to perform proper quality control:
Purchase of secondary external control devices
Complicated multi-step quality control procedure
Use of multiple drops of blood
Costly additional control strips/liquid chemicals
Longer time to complete PT test plus control
Results of control must be recorded/maintained
HemoSense has developed the INRatio monitor, a next generation Point of Care device, to address the many challenges of oral anticoagulant therapy, traditional lab testing, and quality control:
INRatio2 monitor ~ Benefits of the INRatio® System
On Board Quality Control
The INRatio system automatically measures two levels of quality control on each test, eliminating the additional cost, time, and paperwork of a separate control procedure.
No Refrigeration Required
INRatio Test Strips can be stored at room temperature until they expire.
Small Sample Size
One drop (15µL) of fresh whole blood from a fingerstick is applied directly to the strip to perform the test.
Electronic Self-Test
The monitor automatically performs electronic self-tests for battery condition, proper heating range, temperature and memory on each test, assuring the user that the device is working properly.
Procedure Self-Test
The monitor checks for common procedure errors, such as insufficient blood samples, used test strips, or using the monitor outside the proper temperature range. This helps diminish operator error, increasing the likelihood of accurate results.
Fast Results
The monitor reports results within 2 minutes, greatly reducing overall test time and the time-consuming hassle of repeated clinic/lab follow-up.
Easy to Use
The monitor was designed to operate as simply as a telephone, with three easy buttons and a large viewable screen.
Data Communication
The monitor can store 60 test results in memory, and download information to a computer or printer through a simple built-in port.
Portable
The hand-held monitor can be transported easily.
