The International Normalized Ratio (INR) is a "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.[1]

It is a computation based on the prothrombin time (PT) and partial thromboplastin time (PTT).
