As much knowledge as I've acquired, I am still learning. Common sense tells me my INR should be in range all the time and tested at least multiple times week, especially since it takes warfarin so long to affect my INR. Kind of like insulin with a diabetic. Currently, I'm being tested once per week by clinic and when my INR is within range a couple times in a row, then they test every other week.
I'm also self testing, but the clinic still has me call in with machine results. They will not allow me to regulate my own warfarin.
I'm thinking of getting Kay's book. I just have so many specific questions to my case I need answered. I'm wondering how much she talks about in her book.
