What are the appropriate treatments for elevated PT INR?
Asymptomatic patients with an INR that is only slightly above the therapeutic maximum can often be managed simply by omitting their usual warfarin dose and increasing their frequency of INR monitoring. The INR will reduce over several days. Warfarin should be restarted, if necessary, when the INR falls below 5.0.
How is abnormal INR treated?
Vitamin K is a safe and effective antidote to warfarin. Both oral and intravenous (IV) routes are effective in reducing a raised INR due to warfarin with a similar correction of INR by 24 hrs. IV has a more rapid response, within 6-8 hours. Anaphylaxis to IV vitamin K is rare.

What is the function of prothrombin?
Prothrombin is a protein made by the liver. It is one of several substances known as clotting (coagulation) factors.

What Is Coagulation?
Purpose of Testing
- Coagulation studies are used to evaluate blood clotting based on how fast clotting occurs in a sample of blood. All that is required is a simple blood draw. Prior to the test, your healthcare provider may ask you to stop taking certain medications that can affect the results.1 The tests can identify clotting problems and measure your response to therapies such as blood thinners o…
Types of Test
- Two of the tests used in a coagulation study—prothrombin time (PT) and partial thromboplastin time (PTT, also known as aPTT)—can reveal specific things about your health. The third, called the international normalized ratio (INR), is technically a calculation more than it is a test. It is used to assess your response to blood thinners based on the PT.
Risks and Complications
- Blood draws are routine, low-risk procedures. While rare, it is possible to have complications from a blood draw, including: 1. Injection site pain 2. Localized bruising 3. A blood-filled bump (hematoma) at the injection site 4. Lightheadedness or fainting 5. Excessive bleeding (especially if you’re taking blood thinners) 6. Infection (uncommon) If you feel lightheaded during or after a …
Summary
- Coagulation studies involve one or more blood tests that measure how quickly blood clots. The tests can help detect bleeding disorders, check a person’s response to anti-clotting or pro-clotting therapies, and assess a person’s risk for bleeding prior to surgery. Coagulation studies require a simple blood draw. The prothrombin time (PT) test measur...

Uses
- PT INR normal values are helpful guidelines when interpreting the PT INR test result. The test is primarily done to patients who are receiving anticoagulant therapy. Anticoagulants are utilized to prevent inappropriate and dangerous blood clotting which may lead to heart attacks, strokes, cerebrovascular accidents and deep vein thrombosis. People w...
Variations
- The PT INR normal values differ for every individual and depending on a number of factors including medical conditions that result in taking anticoagulants. Normal PT INR values also differ between those who take anticoagulants and those who do not.
Risks
- People who fall short in reaching PT INR normal values should be wary. This is because an abnormal PT INR value is a strong indication that there is a higher possibility for stroke or bleeding to occur. If the PT INR values are found on the higher end of the normal range, bleeding and other related events will likely occur. On the other hand, if the PT INR values are found on th…
Interactions
- Some medications can influence the effects of vitamin K and anticoagulants in a persons body. These include antibiotics, cimetidine, vitamin K supplements, aspirin, barbiturates, hormone replacement therapy and oral contraceptives. Herbal products can also make PT INR levels to become abnormal.
