A system of standardizing the PT [prothrombin time] in oral anticoagulant control was introduced by the World Health Organization in 1983. It is based upon the determination of an International Normalized Ratio (INR) which provides a common basis for communications of PT results and interpretations of therapeutic ranges. The INR is derived from calibrations of commercial thromboplastin reagents against a sensitive human brain thromboplastin, the International Reference Preparation (IRP).
