Prothrombin Time (PT) with International Normalized Ratio (INR) is a blood test that measures the time it takes for blood to clot. The PT test evaluates the activity of certain proteins in the blood that are involved in the clotting process. The INR is a standardized way of expressing the PT results to ensure consistency across different laboratories.
The PT with INR test is commonly used to monitor the effectiveness of blood-thinning medications, such as warfarin, which can help prevent blood clots. By measuring how long it takes for blood to clot, healthcare providers can adjust the dosage of these medications to ensure that blood clots are adequately prevented without causing excessive bleeding.
The PT with INR test is also used to diagnose certain bleeding disorders, monitor liver function, assess the risk of excessive bleeding during surgery, and evaluate the overall clotting ability of the blood.
Results of the PT with INR test are typically reported as the INR value, with the normal range varying depending on the specific medical condition being evaluated. Your healthcare provider will interpret the results and determine if any further action or treatment is necessary based on your individual health profile and medical history.
