What does a low result mean?
Without anticoagulant treatment, an INR near 1.0 is the expected healthy baseline.
What does a high result mean?
For patients on anticoagulant medication, an INR between 2.0 and 3.0 is frequently the intended therapeutic target.
Questions ready for your doctor
Bring these questions to your next consultation to discuss with your healthcare practitioner:
