Why do I need a PT/INR test?
You may need this test if you are taking warfarin on a regular basis. The test helps make sure you are taking the right dose.
If you are not taking warfarin, you may need this test if you have symptoms of a bleeding or clotting disorder.
Symptoms of a bleeding disorder include:
Unexplained heavy bleeding
Bruising easily
Unusually heavy nose bleeds
Unusually heavy menstrual periods in women
Symptoms of a clotting disorder include:
Leg pain or tenderness
Leg swelling
Redness or red streaks on the legs
Trouble breathing
Cough
Chest pain
Rapid heartbeat
In addition, you may need a PT/INR test if you are scheduled for surgery. It helps make sure your blood is clotting normally, so you won't lose too much blood during the procedure.
