Hi there -
Is this something you track daily, or is it periodic? I'm wondering if you can track it as a lab value in your PHR, or if its something more detailed than that. I'm sorry it's been so long, and I am not sure how involved you'd need this to be.
Just today (4/3/11) I suggested an INR/coumadin dosage tracker. I had no idea this had already been suggested and hasn't happened in 3 years!
I am very hard to regulate on coumadin. I'm tested twice a week. Right now I'm on 10mg Mon - Fri, and 7.5mg on Sat/Sun. I've had a DVT and 2 pulmonary embolisms so this is so important to me. This is one of the primary reasons I came to this site!
