Effect of stress on international normalized ratio during warfarin therapy.
OBJECTIVE To discuss the effect of stress on the international normalized ratio (INR) when patients are taking warfarin. CASE SUMMARY Two patients at a pharmacist-managed anticoagulation clinic who were stable with anticoagulation developed elevated INR values after a stressful event occurred. All other factors known to elevate the INR were unchanged; furthermore, the INR values returned to t...
متن کاملFalsely elevated prothrombin international normalized ratio values.
International normalized ratio (INR) monitoring is essential during oral anticoagulation therapy to minimize bleeding complications and thrombotic events. Laboratory technicians cannot differentiate falsely elevated INR results due to problems in drawing blood from truly elevated INR values, but the extent of this phenomenon is unclear. We determined the proportion of patients with INR values o...
متن کاملPoint of Care Prothrombin Time/International Normalized Ratio Devices for Monitoring Warfarin Therapy SCOPE The FDA has become aware of performance problems associated with point of care (POC) Prothrombin Time (PT)/International Normalized Ratio
The FDA has become aware of performance problems associated with point of care (POC) Prothrombin Time (PT)/International Normalized Ratio (INR) devices that raise patient safety concerns. Numerous reports of serious adverse events for POC PT/INR devices have been submitted to the FDA. The FDA’s postmarket analysis of these reports indicates that the adverse events appear to be linked to inaccur...

The Laboratory then provided the INR value at a physician's request. A six month review of prothrombin time (PT) results showed that only the physicians from the Cardiology Clin...
