DW was just diagnosed with A Fib. She takes Xarelto so no blood testing is needed. We considered warfarin and decided the other meds were the best way for her. There is a meter and test strips you can buy so you can run your own PTs and report the levels to your doctor. This is one
PT Meter, the down side is these are expensive to purchase but they do offer some degree of freedom. I have no idea if insurance would cover some or all of the cost.
I have heard of people having standing orders at a national lab chain (like Quest) and just arranging testing that way. There are ways to do this and still have the ability to travel.
Best of luck,
Doug
