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
