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 کاملPoor agreement among prothrombin time international normalized ratio methods: comparison of seven commercial reagents.
BACKGROUND Prothrombin time (PT) has long been the most popular test for monitoring oral anticoagulation therapy. The International Normalized Ratio (INR) was introduced to overcome the problem of marked variation in PT results among laboratories and the various recommendations for patient care. According to this principle, all reagents should be calibrated to give identical results and the sam...
متن کاملReemergence of the International Normalized Ratio for the standardization of prothrombin time.
A survey of physicians demonstrated that half had knowledge of the International Normalized Ratio (INR) but none used the value for monitoring their patients because it was not available from the Coagulation Laboratory. 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...
