My wife needed this testing weekly and we had some trouble with it while traveling. Some places were easy; just stop at a small town hospital and show the prescription from our doctor. Cities in other provinces were more problematic. In Toronto, DW was required to get an order from a local doc which involved a few hours wait, then more hours at the testing place. There was never a charge, fully covered by Alberta health care. We resolved to purchase our own testing tool, which was hundreds of dollars but would have definitely been worth it.
Forum discussion on self testing Fortunately DW was changed to one of the newer, better anticoagulant drugs. It is extremely stable and does not require testing. It is probably more expensive and not suited to every condition.
