Common "Inr" queries answered by top doctors | iCliniq

Inr

INR is called the international normalized ratio. INR is checked for the patients taking anticoagulants. INR is assessed by taking the prothrombin time test, which tells the blood's ability to form clots. With an intake of Warfarin (and other anticoagulants), the INR lies between 2.0 to 3.0. Without taking anticoagulants, the PT time lies between 11 to 13 seconds, and the INR lies between 0.8 to 1.2.
