Alere INRatio Replacement Monitor Model Number: 0100137 Usage: The INRatio 2 PT Monitoring system is used for the quantitative measurement of Prothrombin Time (PT) in fresh, capillary whole blood. The INRatio 2 PT Monitoring system is intended for use outside the body (in vitro diagnostic use) by people taking warfarin and other oral anticoagulant (blood thinning) therapy who need to monitor the clotting time of their blood. The INRatio 2 PT Monitoring System is not intended to be used for screening purpose.

Reason: Alere San Diego is initiating a voluntary recall for the Alere INRatio¿/INRatio¿2 PT/INR Monitoring Systems (Test Strips and Meters). This action is being initiated as a result of patients who had a therapeutic or near-therapeutic INR with the Alere INRatio¿/INRatio¿2 PT/INR Monitoring System but a significantly higher INR (outside of therapeutic range) when performed by a central laboratory.
