PT / INR Testing

Prothrombin time (PT) is used to determine the ability of your blood to properly clot when you are bleeding.  It's commonly done before surgical procedures.

International Normalized Ratio (INR) monitors how effective blood-thinning drugs are, such as Coumadin.  When someone has ongoing inappropriate clotting, a blood thinner is often prescribed.  This often includes people who have had strokes, heart attacks, or deep vein thrombosis.

Your PT/INR may be checked if you are taking a blood thinner, or if people who do not take blood thinners suffer from bleeding disorders (nosebleeds, bruising, heavy menstruation, bleeding gums, or blood in your stool and urine).  In some cases, the PT is recommended by a doctor when surgery is going to be performed, to make sure that your blood will clot properly during the procedure.
