Blood clotting is a natural process your body enacts to stop bleeding. When you get a cut, your body sends cells, called platelets, to the damaged area, followed by proteins, called clotting factors. Your proteins and clotting factors combine to form a solid mass, called a blood clot, which stops the bleeding.
Some people have complications with their clotting factors, however. This causes them to bleed too easily or to get clots when they shouldn’t.
A prothrombin time (PT) test is a diagnostic that your doctor administers to measure how quickly the liquid portion of your blood clots. International normalized ratio is a ratio that’s used to express the results from your PT test. The purpose of the INR is to standardize measurements and test results across different laboratories.
The most common reason for ordering a PT test is to monitor your blood if you’re taking warfarin, a blood-thinning medication that’s used to prevent blood-clot-related conditions like pulmonary embolism or deep venous thrombosis. The PT test can help your doctor determine whether you’re taking the appropriate dose of medication.
Some other reasons your doctor might order a PT INR test is to look for signs of:
Evaluating your clotting ability with a PT test is also helpful in determining your suitability for surgery.
A PT INR test isn’t any more complicated than a simple blood draw. Your provider takes a blood sample (either with a syringe or a finger-prick device) and sends it to a lab for testing.
The diagnostic laboratory then measures how quickly your blood clots. Depending on the lab, you could get your results back within hours, or it could take a few days. Normal blood takes between 10-14 seconds to clot. If your sample takes more or less time, your doctor might order more tests to determine the cause.
