What is PT / INR ?

The PT / INR or prothrombin time/international normalized ratio test helps you determine if your blood is clotting properly. You can also check if the medicine is working well if you are taking certain medications, such as warfarin. This way, you can be sure of taking the right dose of medicine.

In more detail, PT measures the time it takes for the blood sample to clot. The result obtained for PT is used to calculate the international normalized ratio. As a result of bleeding or injury, the clotting process begins. The clotting process involves a set of sequential chemical reactions called coagulation cascades. The proteins and factors involved at each stage must function properly to form a clot and stop the bleeding. Too little can lead to extreme bleeding; too much may lead to extreme clotting. PT test evaluates the amount and function of coagulation factors that are an important part of blood clot formation.


When to get tested?

You will need PT/INR if:

  • You are taking the anticoagulant drug warfarin
  • You have symptoms of excessive bleeding or clotting, such as easy bruising, nosebleeds, or blood clot in a vein or artery
  • You must subject to surgery with an increased risk of blood loss

What does the test result mean?

Prothrombin time may be reported in seconds. In this case, the average time for blood clot formation is 10 to 13 seconds. The higher the number, the longer it takes for the blood to clot. Conversely, a decrease in the number indicates that the blood is clotting faster than usual.

If Prothrombin time is reported based on INR:

  • An INR of 1.1 or below is normal.
  • An INR between 2.0 to 3.0 is an effective therapeutic range for people taking warfarin.
  • Higher INR means that your blood clots more slowly than desired.
  • Lower INR means the blood clots more quickly than usual.


What Foods and Drinks Make your INR Go up and down?

What you eat and drink might also have an impact on your INR.

  • The more regular you are in your eating and drinking habits, the easier it will be to adjust your Warfarin dose and maintain your INRs in range.
  • Limit your consumption of alcohol and alcohol-containing over-the-counter medications.
  • All alcoholic beverages might enhance your INR and raise your risk of bleeding.
  • Leafy green vegetables might speed up the clotting process, resulting in a lower INR. Herbal medicines may include vitamin K or C, both of which influence coagulation.
  • You don’t have to quit all your favorite foods and beverages, but ensure the anticoagulation clinic staff knows what you normally eat and drink. And notify them if this changes. Your information packet can find more information on how foods and Warfarin interact.
  • Fever, dehydration, and sickness, particularly chronic diseases, can alter Warfarin’s effects.
  • A closer relationship between you and the anticoagulation clinic personnel may be required if you are sick.
  • Contact the medical staff and inform them if you have any upcoming dental work, testing, or surgery. We may need to alter your Warfarin dose to bring you to the amount your provider says is safe for the surgery you’ll be having.
  • Both prescription and over-the-counter medications can alter how Warfarin works for you. Do not take any medications, including over-the-counter medications, until you have discussed them with your physician or pharmacist. When using Warfarin, drugs in the aspirin family might cause excessive bleeding. These include OTC medications and natural remedies for pain, inflammation, colds, and allergies.
  • Aspirin can be really beneficial in some cases. It is safe to take aspirin if your physician has expressly instructed you to do so.
  • Low-dose acetaminophen, including Tylenol, is safe to use while taking Warfarin. Please notify your physician, pharmacist, or anticoagulation clinic nurse if you use more than 7 normal strength pills of these pain relievers each week. More information about interactions between Warfarin and other medicines may be found in your information packet.


What foods and medications affect the test result?

Taking the following medications can affect the test result:

  • Antibiotics
  • Barbiturates
  • Oral contraceptives
  • Hormone-replacement therapy (HRT)
  • vitamin K


Consumption of the following foods can also affect test results:

  • Alcohol
  •  Beef
  •  Pork liver
  •  Green tea
  • Broccoli
  •  Chickpeas
  •  Kale
  • Turnip greens
  • Soybean products

So remember to let your healthcare provider know about any medications, foods, and supplements you have recently taken before the test.


What is INR monitoring?

Patients on lifetime anticoagulation and long-term therapy can use INR monitoring to measure the level of their INR, which stands for International Normalized Ratio. Patients can do the test on their own rather than visiting a clinic or health center. The test helps detect and diagnose a bleeding disorder or excessive clotting disorder. 

You can use a portable INR monitor like the one used in clinics to take and test a drop of your blood. The device draws blood out of the finger and records the INR level measured by the monitor. 

If the elderly need to check the INR level but can’t do it on their own, our caregiver or skilled nurse can do it for them. The test is risk-free and doesn’t pose any pain to your loved ones. The seniors might forget or not be in the mood to do the test. A caregiver or nurse in your place of residence completes it in the best way. 

The home pt INR monitoring system enables you to check the INR level without the need to visit a clinic or a health center. It’s quick, and the result is accurate. The elderly, patients or the disabled might not be able to do it on their own. They could hurt themselves. 


What does low INR mean?

When the level of your INR is higher than the recommended range, it denotes that your blood clots more slowly than the standards. A too low INR level could pose the risk of a blood clot. However, a low INR means that your blood clots more quickly than the standards. A high level of INR could increase the possibility of bleeding. 

Diet and the medicine taken have an impact on the level of INR. Our caregivers can check the INR level and recommend diet changes to decrease or increase the INR level. 

The following reduce your INR level:

  • Vitamin k excess intake
  • Drugs
  • Antacids
  • Antidepressant
  • Antiepileptic drugs
  • Antifungal
  • Antipsychotics
  • Antitubercular
  • Barbiturate


A PT/INR machine 

The A PT/INR machine measures the duration it takes a person’s blood to clot. It takes a drop of blood from the patient’s finger-stick using a lancet. Then the machine analyzes the sample of blood put on a test strip. It analyzes the PT and the INR. 

The machine is particularly helpful for people who take warfarin. Determining the effects of warfarin on the clotting system is helpful for patients who have had heart surgery or other groups. 

Our caregivers help you to measure the INR level with the A PT/INR machine. 


What is a PT/INR tester?

The INR tester or blood INR tester measures the duration it takes a person’s blood to clot used for warfarin monitoring. It takes a drop of blood from the patient’s finger-stick using a lancet. Then the tester analyzes the sample of blood put on a test strip. It analyzes the PT and the INR. 

The PT/INR tester is particularly helpful for warfarin monitoring of people. Determining the effects of warfarin on the clotting system is helpful for patients who have had heart surgery or other groups.

Does Medicare cover an INR?

Medicare beneficiaries with chronic atrial fibrillation or venous thromboembolism who are taking warfarin, an anticoagulant (blood thinner) medication, can now receive home blood testing of prothrombin time (PT) International Normalized Ratio (INR).
