Falsely 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 کاملCorrelation of point-of-care International Normalized Ratio to laboratory International Normalized Ratio in hemodialysis patients taking warfarin.
BACKGROUND AND OBJECTIVES To determine whether point-of-care (POC) International Normalized Ratio (INR) test results correlate with plasma INR measures in intermittent hemodialysis (IHD) patients on warfarin. Anemia is thought to reduce the accuracy of POC INR assay results. Whether POC INR testing could be implemented for hemodialysis patients on chronic warfarin, who are often anemic despite ...
متن کاملEffect 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 کاملWarfarin Dosing and Time Required to Reach Therapeutic International Normalized Ratio in Patients with Hypercoagulable Conditions
OBJECTIVE The purpose of this study was to analyze the difference in duration of anticoagulation and dose of warfarin required to reach a therapeutic international normalized ratio [(INR) of 2 to 3] in patients with hypercoagulable conditions as compared to controls. To our knowledge, this study is the first in the literature to delineate such a difference. MATERIALS AND METHODS A retrospecti...
