International Normalized Ration (INR) Calculation

A system, commonly called the INR, International Normalized Ratio, for reporting the results of blood coagulation (clotting) tests. PT/INR should be checked to ensure that the patient maintains the proper level of anticoagulation. The prothrombin time (PT or protime) is the actual time calculation, measured in seconds, for an anticoagulated sample of plasma or whole blood to clot after it is added to a thromboplastin reagent. This calculator is used to neasure the INR.

Formula:

(INR=(PT patient/PT normal)ISI) PT patient = patient's measure PT (seconds) PT normal = laboratory's geometric mean value for normal patients (seconds) ISI = International Sensitivity Index
