Assessing Random Error in the International Normalized Ratio
Therapeutic Drug Monitoring, 1994Changes in the international normalized ratio (INR) following warfarin administration may be explained not only by the attendant anticoagulant effect but also, in part, by random errors normally associated with laboratory assays. Thus, a patient's true INR will differ from the reported value by some random error related to the variability in the ...

International Normalized Ratio: Towards Improved Accuracy
Thrombosis and Haemostasis, 1999Oral anticoagulants such as warfarin, acenocoumarin, and phenprocoumon induce depletion of vitamin K-dependent coagulation factors, causing prolongation of the prothrombin time (PT) and the International Normalized Ratio (INR). Commercially available thromboplastin reagents used for the determination of the PT vary in their response to coagulation ...

Effect of warfarin nonadherence on control of the International Normalized Ratio
American Journal of Health-System Pharmacy, 2004The frequency and causes of ab- errant International Normalized Ratios (INRs) in warfarin recipients and the percentage explainable by warfarin nonadherence were studied.The medical records of patients whose warfarin therapy was monitored by a telephone-based anticoagulation service in a Midwestern urban hospital between March 2000 and March 2001 were ...
