Exactly! What he said.Can you cite a source that says that testing every two weeks is a best practice? A stroke can occur in as few as ten days if the INR is too low (according to a Duke University Clinic's report). I believe that in the U.K. and much of Europe, the accepted practice, and the way that patients are able to maintain their INRs is to test weekly.
And you said 'my INR strip provider will send you a few extra strips .' Why whould your provider send me strips?
The anticoagulation clinics often use outdated protocols for managing INR. These are the same people who advocate for testing monthly or even every other month if a patient's INR is stable.
Once weekly testing is safer than every two weeks.
