What is INR used for?
INR, or International Normalized Ratio, measures blood clotting time and is used to monitor the effectiveness of anticoagulant therapy like warfarin.
How do I interpret my INR result?
A target INR range for warfarin therapy is typically between 2.0 and 3.0. Results outside this range may indicate a need to adjust your medication dosage.
What factors can affect my INR level?
Factors such as diet, particularly vitamin K intake, certain medications, and liver function can affect your INR level.
How often should I get my INR checked?
Frequency of INR testing depends on your individual health condition and response to warfarin. Your healthcare provider will determine the best schedule for you.
What is the difference between PT and INR?
PT, or Prothrombin Time, is a raw test result. INR standardizes this result using an international control plasma value to ensure consistency across different laboratories.
Can I calculate my INR at home?
Home INR testing kits are available, but it’s important to follow the manufacturer’s instructions and consult with your healthcare provider for accurate results.
What should I do if my INR is too high or too low?
If your INR is too high (above target range), you may need to reduce your warfarin dose. If it’s too low, your doctor might increase the dosage. Always consult with your healthcare provider for personalized advice.
