Prothrombin Time (PT) with INR


The Prothrombin Time with INR Test, often referred to as a PT with INR test, measures the amount of time it takes your blood to clot when various reagents are added. In order for your blood to clot properly, a series of proteins or clotting factors must react accordingly in a particular order. If one or more of these factors isn’t performing as it should, your body may struggle to stop itself from bleeding excessively. Knowing these figures can help physicians diagnose clotting or bleeding disorders. This Prothrombin Time with INR Test can be extremely valuable information should you ever require surgery.
