Affected Products
Alere INRatio2 PT/INR Professional Monitoring System Model Number: 55128A Product Usage: The Alere INRatio¿/INRatio¿2 system uses a modified version of the one-stage PT test. After a drop of blood is applied to the test strip, it is drawn into the test area and mixed with reagents that initiate coagulation. When the blood clots, changes in impedance in the sample are detected by the monitor. The monitor calculates the PT and INR results from this impedance change and reports them on the display. The Alere INRatio/INRatio2 PT/INR Monitoring System is used for the quantitative measurement of Prothrombin Time (PT) in fresh, capillary whole blood. The Alere INRatio/INRatio2 PT/INR Monitoring System is intended for use outside the body (in vitro diagnostic use). The Alere INRatio/INRatio2 PT/INR Monitoring System is intended for professional and home use by people taking warfarin and other oral anticoagulant (blood thinning) therapy who need to monitor the clotting time of their blood. The Alere INRatio/INRatio2 PT/INR Monitoring System is not intended to be used for screening purposes.
