Introduction to Prothrombin Time (PT INR) Test 

Our liver produces a protein called Prothrombin, which plays a crucial role in blood clotting. The prothrombin time test (PTT) allows doctors to assess how long it takes for blood to clot. Other names for the test include the PT INR test and pro time. 

Your doctor may recommend the test to monitor the speed of your blood clots. They can also suggest if you are taking warfarin (a blood thinner). A healthcare professional can also perform this test to check liver disease. Redcliffe Labs can assist if they suspect health issues and suggest a blood test. Our professionals ensure that we provide timely and accurate PT INR test reports. 

Test Details of Prothrombin Time Test 

Symptoms of PT INR Test

The PT INR test means that blood is clotting normally. Platelets create a plug around the wound to stop bleeding. In some cases, the body creates incorrect coagulation factors. It could be because of liver disease, vitamin K deficiency, or blood clots. 

Some common symptoms of PT INR blood test are: 

• Heavy periods 
• Blood in the urine
• Uncontrollable bleeding 
• Easy bruising 
• Nosebleeds
• Swollen or painful joints 
• Heavy nose bleeding 
• Leg pain or swelling 
• Skin that feels warm 
• Trouble in breathing 
• Chest pain 
• Fast heartbeat
• Cough 
• Redness or darkening of the leg 

Doctors can prescribe testing-

• Before performing any surgery. To determine the functionality of blood clotting. 
• Suspecting a bleeding disorder 
• As a normal routine checkup 
• If you are taking warfarin 

Purpose of Prothrombin Test 

The Prothrombin time test helps identify the time blood takes to clot. Doctors suggest the PT/INR test to find out: when we get a cut or puncture at a site on hand, our blood vessel ruptures.

• Monitor the level of warfarin (a blood-thinning medicine).
• Reason for abnormal blood clots. 
• Unusual bleeding
• Clotting ability before surgery 
• Identify any liver problem
• Check vitamin K deficiency

Other Test Doctor Might Suggest

After the PT INR test, the doctor might suggest other tests. It completely depends on what the doctor is looking for. Moreover, to detect any liver disease or cause of bleeding disorder, they might suggest the following tests: 

• PTT test
• APTT test 
• Platelet count 
• Thrombin time test 
• von Willebrand factor tests 

What Does The Prothrombin Test Measure?

The Prothrombin time test measures the time it takes for blood to clot. The test results may differ based on the lab and the test method. It is crucial to get tested by a trusted lab, Redcliffe Labs. 

The test results can be utilized to calculate an International Normalized Ratio (INR). A doctor can perform a PT INR blood test to determine liver condition and blood clotting disorder before surgery.

PT INR Test Normal Range

The prothrombin test measures the time it takes for blood to form a clot. The reports show results in seconds and INR (International Normalized Ratio). Results vary if you are taking warfarin (a blood-thinning medicine). 

The PT INR test normal range for warfarin consumers is an INR of 2.0 to 3.0, while for non-warfarin consumers, PT is 11 to 13.5 seconds, and INR is 0.8 to 1.1. 

Note- The normal range of PT varies based on lab equipment. Consult your doctor about which report is right for you. 

What Does The Prothrombin Results Indicate?

Your health is stable if the PT INR test reports showcase a normal range. Still, consider going for other tests, such as the APTT test. Abnormal report results could be due to many reasons. 

Reason for too slow clotting

• Liver problem 
• Inadequate level of protein 
• Vitamin K deficiency
• Excess waste substances in the body
• Blood-thinning medicine 

Reason for too fast clotting 

• Supplements with vitamin K 
• Food with high vitamin K, such as liver, green tea, chickpeas, turnip greens, and broccoli. 
• Medicines containing estrogen, including birth control pills and hormone replacement therapy.

Other reasons for abnormal results 

• Bleeding disorder 
• Disseminated Intravascular Coagulation disorder (blood clotting protein becomes overactive)
• Liver disease 
• Wrong dose of medicine
• Consumption of alcohol 
• Certain food 
• Certain medicines, supplements, vitamins, antibiotics, cold therapy, and other medicines. 

Who Should Take The PT INR Test?

The PT INR test, which stands for Prothrombin Time International Normalized Ratio, is a blood test. It is used to evaluate how well and how quickly your blood clot. It is crucial for managing and monitoring conditions that affect blood clotting. Here are some key groups of people who should take the PT INR test:

• Individuals on Anticoagulant Therapy- Warfarin: People prescribed warfarin need regular PT INR tests to ensure their blood clotting levels are within a therapeutic range. 

• Patients with a History of Blood Clots- Those with conditions such as deep vein thrombosis (DVT), pulmonary embolism (PE), or atrial fibrillation may require a Prothrombin test to monitor the effectiveness of their anticoagulant medication.

• Individuals with Certain Heart Conditions- People with atrial fibrillation need regular PT INR monitoring.

• Patients Preparing for Surgery or Medical Procedures- Doctors might use the PT INR test to ensure that blood clotting levels are appropriate before certain surgeries or medical procedures. 

• People with Liver Disease- The PT INR blood test monitors & manages the risk of bleeding complications associated with liver conditions.

• Patients with Vitamin K Deficiency- Vitamin K is essential for blood clotting, so that deficiencies can lead to prolonged PT INR.

• Individuals with Genetic Clotting Disorders- People with conditions such as Factor V Leiden mutation or antiphospholipid syndrome may need a PT INR test as part of their management plan.

• Pregnant Women with Certain Conditions- Pregnant women who are at risk of blood clots.

• People Taking Certain Medications- Some medications can interact with anticoagulants and affect PT INR levels. Regular testing helps manage these interactions and adjust dosages.

• Routine Health Checks for High-Risk Populations—The PT INR test might be part of routine health checks for people who are at high risk of clotting or bleeding disorders. 

How Often Should the Test Be Done?

The frequency of PT INR testing varies depending on individual circumstances:

• For those on stable anticoagulant therapy, they can test every 4-6 weeks. 
• More frequent testing may be required for those with fluctuating PT INR levels.
• Before surgery or medical procedures.
