What does it mean when PT and INR are high?

PT/INR too high- If a PT/INR test result is too high, it means that the persons’ blood is clotting too slowly, and is at risk of bleeding; their dose of warfarin is too high. On the other hand, if the PT/INR test result is too low, their dose of warfarin may not be enough to protect the blood from clotting.

What would cause PT INR to be high?

If your INR is above 1.1, your blood is clotting more slowly than normal. Causes of this include: Bleeding disorders. A disorder called disseminated intravascular coagulation, in which the proteins that control blood clotting are overactive.

What happens when prothrombin time is high?

When the PT is high, it takes longer for the blood to clot (17 seconds, for example). This usually happens because the liver is not making the right amount of blood clotting proteins, so the clotting process takes longer. A high PT usually means that there is serious liver damage or cirrhosis.

What level of INR is too high?

A value higher than 3.5 increases the risk of bleeding problems. Many things can affect the way warfarin works. Some natural health products and other medicines can make warfarin work too well. That can raise the risk of bleeding.

How do you treat high INR?

The treatment options for patients who have been over-anticoagulated are:

1. Dose omission;
2. Oral phytomenadione (vitamin K1);
3. Intravenous phytomenadione;
4. Fresh frozen plasma (FFP);
5. Prothrombin complex concentrates (PCC).

What is a critical PT INR level?

[8]For patients who are on anticoagulant therapy, the therapeutic INR ranges between 2.0 to 3.0. INR levels above 4.9 are considered critical values and increase the risk of bleeding.

What are the side effects of a high INR?

What are the signs and symptoms of an elevated INR? You may have small cuts that bleed more than normal, and for longer than normal. You may bruise easily, have frequent nosebleeds, or notice your gums bleeding.

What causes high prothrombin time?

The list of medical condition causes of Increased prothrombin time (Elevated PTT ) includes: Alcohol abuse. Medications. Chronic hepatitis B. Chronic hepatitis C.

What causes low prothrombin time?

Causes: Serious liver diseases can lead to low prothrombin levels, resulting in longer time for clotting. Vitamin K deficiency, blood-thinning medicines, certain other medications, and certain bleeding disorders can affect prothrombin function, as well.

What is a good prothrombin time?

The normal prothrombin time (PT) is approximately 9 to 12 seconds and the normal activated partial thromboplastin time (APTT) is approximately 26 to 36 seconds.

What does high prothrombin time test result mean?

This test checks how quickly your blood clots. A usual prothrombin time test result is 10-14 seconds. Higher than that means your blood is taking longer than normal to clot .
