International Normalized Ratio

The International Normalized Ratio (INR) is a standardized measurement used to assess how quickly your blood clots, especially when you’re on blood-thinning medications like warfarin. It compares your blood's clotting time to a normal value to ensure your medication is working properly. A normal INR is typically around 1.0, meaning your blood clots at a normal rate. If your INR is higher, your blood takes longer to clot, increasing bleeding risk. If it's lower, your blood clots too quickly, raising the risk of clotting issues. Regular monitoring helps doctors adjust medication for safe and effective treatment.
