International normalized ratio (INR) derivation is dependent on the international sensitivity index (ISI) of thromboplastin. It varies with instrument and reagents used.
This article was published in the following journal.
Name: Laboratory medicine
: A number of factors contribute to interlaboratory variation of international normalized ratio (INR) results. This variability can lead to differences in clinical decision-making. This prospective co...
Metopic synostosis results in a keel-shaped forehead, reduced frontal intracranial volume (ICV), and lower frontal to total volume ratio. The ratio improves with cranioplasty, but at 3 years of age, t...
Acute pulmonary embolism (PE) is a serious clinical disease characterized by a high mortality rate. The aim of this study was to assess the prognostic value of international normalized ratio (INR) in ...
To determine the prevalence of international normalized ratio (INR) findings outside the normal range in hospital emergency department patients on vitamin K antagonists (VKAs). To identify factors ass...
Catheter ablation of left atrial arrhythmias on uninterrupted oral anticoagulation with vitamin K antagonists: How is the relationship between international normalized ratio, activated clotting time and procedure-related complications?
Ablation of atrial fibrillation (AF) on uninterrupted phenprocoumon reduces periprocedural thromboembolic and bleeding complications. Heparin is administered intraprocedurally to achieve activated clo...
The goal of this study will be to determine whether PCC confers any benefits over FFP in the traumatic intracranial hemorrhage with respect to multiple factors including time to correction...
The purpose of this study is to assess the measurement conformity of an in vitro diagnostic device measuring the INR (International harmonized Ratio).
The purpose of this study is to evaluate efficacy, safety and tolerance of BERIPLEX® P/N compared with plasma in regard to rapid reversal of coagulopathy induced by coumarin derivatives ...
Long-term anticoagulation is indicated in patients for the prophylaxis and/or treatment of the thromboembolic complications associated with atrial fibrillation and/or mechanical cardiac va...
Investigate the validity of Hemosense System in pediatric patients on anticoagulation therapy.
System established by the World Health Organization and the International Committee on Thrombosis and Hemostasis for monitoring and reporting blood coagulation tests. Under this system, results are standardized using the International Sensitivity Index for the particular test reagent/instrument combination used.
The ratio of two odds. The exposure-odds ratio for case control data is the ratio of the odds in favor of exposure among cases to the odds in favor of exposure among noncases. The disease-odds ratio for a cohort or cross section is the ratio of the odds in favor of disease among the exposed to the odds in favor of disease among the unexposed. The prevalence-odds ratio refers to an odds ratio derived cross-sectionally from studies of prevalent cases.
Ratio of T-LYMPHOCYTES that express the CD4 ANTIGEN to those that express the CD8 ANTIGEN. This value is commonly assessed in the diagnosis and staging of diseases affecting the IMMUNE SYSTEM including HIV INFECTIONS.
Scanning microscopy in which a very sharp probe is employed in close proximity to a surface, exploiting a particular surface-related property. When this property is local topography, the method is atomic force microscopy (MICROSCOPY, ATOMIC FORCE), and when it is local conductivity, the method is scanning tunneling microscopy (MICROSCOPY, SCANNING TUNNELING).
A severity of disease classification system designed to measure the severity of disease for patients aged 15 and over admitted to intensive care units.
